# Deprecated API removed after v2.10 > After reaching end of life, the following deprecated APIs were removed from Flutter. ## Summary In accordance with Flutter's [Deprecation Policy][], deprecated APIs that reached end of life after the 2.10 stable release have been removed. All affected APIs have been compiled into this primary source to aid in migration. A [quick reference sheet][] is available as well. [Deprecation Policy]: https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md#deprecations [quick reference sheet]: /go/deprecations-removed-after-2-10 ## Changes This section lists the deprecations by affected class. --- ### `maxLengthEnforced` of `TextField` & related classes Supported by Flutter Fix: yes `maxLengthEnforced` was deprecated in v1.25. Use `maxLengthEnforcement` instead. Where `maxLengthEnforced` was true, replace with `MaxLengthEnforcement.enforce`. Where `maxLengthEnforced` was false, replace with `MaxLengthEnforcement.none`. This change allows more behaviors to be specified beyond the original binary choice, adding `MaxLengthEnforcement.truncateAfterCompositionEnds` as an additional option. The following classes all have the same change of API: - `TextField` - `TextFormField` - `CupertinoTextField` **Migration guide** [In-depth migration guide available][] Code before migration: ```dart const TextField textField = TextField(maxLengthEnforced: true); const TextField textField = TextField(maxLengthEnforced: false); final lengthEnforced = textField.maxLengthEnforced; const TextFormField textFormField = TextFormField(maxLengthEnforced: true); const TextFormField textFormField = TextFormField(maxLengthEnforced: false); final lengthEnforced = textFormField.maxLengthEnforced; const CupertinoTextField cupertinoTextField = CupertinoTextField(maxLengthEnforced: true); const CupertinoTextField cupertinoTextField = CupertinoTextField(maxLengthEnforced: false); final lengthEnforced = cupertinoTextField.maxLengthEnforced; ``` Code after migration: ```dart const TextField textField = TextField(maxLengthEnforcement: MaxLengthEnforcement.enforce); const TextField textField = TextField(maxLengthEnforcement: MaxLengthEnforcement.none); final lengthEnforced = textField.maxLengthEnforcement; const TextFormField textFormField = TextFormField(maxLengthEnforcement: MaxLengthEnforcement.enforce); const TextFormField textFormField = TextFormField(maxLengthEnforcement: MaxLengthEnforcement.none); final lengthEnforced = textFormField.maxLengthEnforcement; const CupertinoTextField cupertinoTextField = CupertinoTextField(maxLengthEnforcement: MaxLengthEnforcement.enforce); const CupertinoTextField cupertinoTextField = CupertinoTextField(maxLengthEnforcement: MaxLengthEnforcement.none); final lengthEnforced = cupertinoTextField.maxLengthEnforcement; ``` **References** API documentation: * [`TextField`][] * [`TextFormField`][] * [`CupertinoTextField`][] Relevant issues: * [Issue 67898](https://github.com/flutter/flutter/issues/67898) Relevant PRs: * Deprecated in [#68086](https://github.com/flutter/flutter/pull/68086) * Removed in [#98539](https://github.com/flutter/flutter/pull/98539) [In-depth migration guide available]: /release/breaking-changes/use-maxLengthEnforcement-instead-of-maxLengthEnforced [`TextField`]: https://api.flutter.dev/flutter/material/TextField-class.html [`TextFormField`]: https://api.flutter.dev/flutter/material/TextFormField-class.html [`CupertinoTextField`]: https://api.flutter.dev/flutter/cupertino/CupertinoTextField-class.html --- ### `VelocityTracker` constructor Supported by Flutter Fix: yes The default constructor for `VelocityTracker`was deprecated in v1.22. The `VelocityTracker.withKind()` should be used instead. This allows for a `PointerDeviceKind` to be specified for the tracker. The previous default for `VelocityTracker.kind` was `PointerDeviceKind.touch`. **Migration guide** Code before migration: ```dart final VelocityTracker tracker = VelocityTracker(); ``` Code after migration: ```dart final VelocityTracker tracker = VelocityTracker.withKind(PointerDeviceKind.touch); ``` **References** API documentation: * [`VelocityTracker`][] * [`PointerDeviceKind`][] Relevant PRs: * Deprecated in [#66043](https://github.com/flutter/flutter/pull/66043) * Removed in [#98541](https://github.com/flutter/flutter/pull/98541) [`VelocityTracker`]: https://api.flutter.dev/flutter/gestures/VelocityTracker-class.html [`PointerDeviceKind`]: https://api.flutter.dev/flutter/dart-ui/PointerDeviceKind.html --- ### `DayPicker` & `MonthPicker` Supported by Flutter Fix: no The `DayPicker` and `MonthPicker` widgets were first deprecated in v1.15, and then extended in v1.26. They have been replaced by one comprehensive widget, `CalendarDatePicker`. These widgets were displayed using the `showDatePicker` method. This method was migrated to present the new `CalendarDatePicker` before this release, and so their final removal should not necessitate further action. **References** Design document: * [Material Date Picker Redesign][] API documentation: * [`CalendarDatePicker`][] * [`showDatePicker`][] Relevant issues: * [Issue 50133](https://github.com/flutter/flutter/issues/50133) Relevant PRs: * Deprecated in [#50546](https://github.com/flutter/flutter/issues/50546) * Removed in [#98543](https://github.com/flutter/flutter/issues/98543) [Material Date Picker Redesign]: /go/material-date-picker-redesign [`CalendarDatePicker`]: https://api.flutter.dev/flutter/material/CalendarDatePicker-class.html [`showDatePicker`]: https://api.flutter.dev/flutter/material/showDatePicker.html --- ### `FlatButton`, `RaisedButton`, & `OutlineButton` Supported by Flutter Fix: no The `FlatButton`, `RaisedButton`, and `OutlineButton` widgets were first deprecated in v1.20, and then extended in v1.26. They are replaced by new buttons, `TextButton`, `ElevatedButton`, and `OutlinedButton`. These new widgets also use new associated themes, rather than the generic `ButtonTheme`. | Old Widget | Old Theme | New Widget | New Theme | |-----------------|---------------|------------------|-----------------------| | `FlatButton` | `ButtonTheme` | `TextButton` | `TextButtonTheme` | | `RaisedButton` | `ButtonTheme` | `ElevatedButton` | `ElevatedButtonTheme` | | `OutlineButton` | `ButtonTheme` | `OutlinedButton` | `OutlinedButtonTheme` | {:.table .table-striped .nowrap} **Migration guide** [In-depth migration guide available for detailed styling][] Code before migration: ```dart FlatButton( onPressed: onPressed, child: Text('Button'), // ... ); RaisedButton( onPressed: onPressed, child: Text('Button'), // ... ); OutlineButton( onPressed: onPressed, child: Text('Button'), // ... ); ``` Code after migration: ```dart TextButton( onPressed: onPressed, child: Text('Button'), // ... ); ElevatedButton( onPressed: onPressed, child: Text('Button'), // ... ); OutlinedButton( onPressed: onPressed, child: Text('Button'), // ... ); ``` **References** Design document: * [New Material buttons and themes][] API documentation: * [`ButtonStyle`][] * [`ButtonStyleButton`][] * [`ElevatedButton`][] * [`ElevatedButtonTheme`][] * [`ElevatedButtonThemeData`][] * [`OutlinedButton`][] * [`OutlinedButtonTheme`][] * [`OutlinedButtonThemeData`][] * [`TextButton`][] * [`TextButtonTheme`][] * [`TextButtonThemeData`][] Relevant PRs: * New API added in [#59702](https://github.com/flutter/flutter/issues/59702) * Deprecated in [#73352](https://github.com/flutter/flutter/issues/73352) * Removed in [#98546](https://github.com/flutter/flutter/issues/98546) [In-depth migration guide available for detailed styling]: /release/breaking-changes/buttons [New Material buttons and themes]: /go/material-button-migration-guide [`ButtonStyle`]: https://api.flutter.dev/flutter/material/ButtonStyle-class.html [`ButtonStyleButton`]: https://api.flutter.dev/flutter/material/ButtonStyleButton-class.html [`ElevatedButton`]: https://api.flutter.dev/flutter/material/ElevatedButton-class.html [`ElevatedButtonTheme`]: https://api.flutter.dev/flutter/material/ElevatedButtonTheme-class.html [`ElevatedButtonThemeData`]: https://api.flutter.dev/flutter/material/ElevatedButtonThemeData-class.html [`OutlinedButton`]: https://api.flutter.dev/flutter/material/OutlinedButton-class.html [`OutlinedButtonTheme`]: https://api.flutter.dev/flutter/material/OutlinedButtonTheme-class.html [`OutlinedButtonThemeData`]: https://api.flutter.dev/flutter/material/OutlinedButtonThemeData-class.html [`TextButton`]: https://api.flutter.dev/flutter/material/TextButton-class.html [`TextButtonTheme`]: https://api.flutter.dev/flutter/material/TextButtonTheme-class.html [`TextButtonThemeData`]: https://api.flutter.dev/flutter/material/TextButtonThemeData-class.html --- ### `Scaffold` `SnackBar` methods Supported by Flutter Fix: no The following `Scaffold` `SnackBar` methods were deprecated in v1.23. - `showSnackBar` - `removeCurrentSnackBar` - `hideCurrentSnackBar` The same named methods of the `ScaffoldMessenger` should be used instead. A default `ScaffoldMessenger` is already created in every `MaterialApp`. **Migration guide** [In-depth migration guide available][] Code before migration: ```dart Scaffold.of(context).showSnackBar(mySnackBar); Scaffold.of(context).removeCurrentSnackBar(mySnackBar); Scaffold.of(context).hideCurrentSnackBar(mySnackBar); ``` Code after migration: ```dart ScaffoldMessenger.of(context).showSnackBar(mySnackBar); ScaffoldMessenger.of(context).removeCurrentSnackBar(mySnackBar); ScaffoldMessenger.of(context).hideCurrentSnackBar(mySnackBar); ``` **References** Design document: * [ScaffoldMessenger Design][] Video content: * [SnackBar Delivery][] * [Widget of the Week][] API documentation: * [`ScaffoldMessenger`][] * [`SnackBar`][] Relevant issues: * [Issue 57218](https://github.com/flutter/flutter/issues/57218) * [Issue 62921](https://github.com/flutter/flutter/issues/62921) Relevant PRs: * New API added in [#64101](https://github.com/flutter/flutter/issues/64101) * Deprecated in [#67947](https://github.com/flutter/flutter/issues/67947) * Removed in [#98549](https://github.com/flutter/flutter/issues/98549) [In-depth migration guide available]: /release/breaking-changes/scaffold-messenger [ScaffoldMessenger Design]: /go/scaffold-messenger [SnackBar Delivery]: https://youtu.be/sYG7HAGu_Eg?t=10271 [Widget of the Week]: https://youtu.be/lytQi-slT5Y [`ScaffoldMessenger`]: https://api.flutter.dev/flutter/material/ScaffoldMessenger-class.html [`SnackBar`]: https://api.flutter.dev/flutter/material/SnackBar-class.html --- ### `RectangularSliderTrackShape.disabledThumbGapWidth` Supported by Flutter Fix: yes The `RectangularSliderTrackShape.disabledThumbGapWidth` was first deprecated in v1.5, and then extended in v1.26. This was no longer used by the framework, as the animation of the slider thumb no longer occurs when disabled. **Migration guide** Code before migration: ```dart RectangularSliderTrackShape(disabledThumbGapWidth: 2.0); ``` Code after migration: ```dart RectangularSliderTrackShape(); ``` **References** API documentation: * [`RectangularSliderTrackShape`][] Relevant PRs: * Animation changed in [#30390](https://github.com/flutter/flutter/issues/30390) * Deprecated in [#65246](https://github.com/flutter/flutter/issues/65246) * Removed in [#98613](https://github.com/flutter/flutter/issues/98613) [`RectangularSliderTrackShape`]: https://api.flutter.dev/flutter/material/RectangularSliderTrackShape-class.html --- ### Text selection of `ThemeData` to `TextSelectionThemeData` Supported by Flutter Fix: yes The following `ThemeData` members were first deprecated in v1.23, and extended in v1.26. - `useTextSelectionTheme` - `textSelectionColor` - `cursorColor` - `textSelectionHandleColor` These should be replaced by a more comprehensive `TextSelectionThemeData`, which is now specified in `ThemeData` itself. The `useTextSelectionTheme` flag served as a temporary migration flag to distinguish the two APIs, it can be removed now. **Migration guide** [In-depth migration guide available][] Code before migration: ```dart ThemeData( useTextSelectionTheme: false, textSelectionColor: Colors.blue, cursorColor: Colors.green, textSelectionHandleColor: Colors.red, ); ``` Code after migration: ```dart ThemeData( textSelectionTheme: TextSelectionThemeData( selectionColor: Colors.blue, cursorColor: Colors.green, selectionHandleColor: Colors.red, ), ); ``` **References** Design document: * [Text Selection Theme][] API documentation: * [`ThemeData`][] * [`TextSelectionThemeData`][] Relevant issues: * [Issue 17635](https://github.com/flutter/flutter/issues/17635) * [Issue 56082](https://github.com/flutter/flutter/issues/56082) * [Issue 61227](https://github.com/flutter/flutter/issues/61227) Relevant PRs: * New API added in [#62014](https://github.com/flutter/flutter/issues/62014) * Deprecated in [#66485](https://github.com/flutter/flutter/issues/66482) * Removed in [#98578](https://github.com/flutter/flutter/issues/98578) [In-depth migration guide available]: /release/breaking-changes/text-selection-theme [Text Selection Theme]: /go/text-selection-theme [`ThemeData`]: https://api.flutter.dev/flutter/material/ThemeData-class.html [`TextSelectionThemeData`]: https://api.flutter.dev/flutter/material/TextSelectionThemeData-class.html --- ### `RenderEditable.onSelectionChanged` to `TextSelectionDelegate.textEditingValue` Supported by Flutter Fix: no `RenderEditable.onSelectionChanged` and `TextSelectionDelegate.textEditingValue` were deprecated in v1.26. Instead of calling one or both of these methods, call `TextSelectionDelegate.userUpdateTextEditingValue`. This fixed a bug where the `TextInputFormatter` would receive the wrong selection value. **Migration guide** Code before migration: ```dart renderEditable.onSelectionChanged(selection, renderObject, cause); textSelectionDelegate.textEditingValue = value; ``` Code after migration: ```dart textSelectionDelegate.userUpdateTextEditingValue(value, cause); ``` **References** API documentation: * [`RenderEditable`][] * [`TextSelectionDelegate`][] Relevant issues: * Resolved [#75505](https://github.com/flutter/flutter/issues/75502) Relevant PRs: * Deprecated in [#75541](https://github.com/flutter/flutter/issues/75541) * Removed in [#98582](https://github.com/flutter/flutter/issues/98582) [`RenderEditable`]: https://api.flutter.dev/flutter/rendering/RenderEditable-class.html [`TextSelectionDelegate`]: https://api.flutter.dev/flutter/services/TextSelectionDelegate-mixin.html --- ### `Stack.overflow` Supported by Flutter Fix: yes `Stack.overflow`, as well as the `Overflow` enum were deprecated in v1.22. The replacement is `Stack.clipBehavior`, a change made as part of unifying clip behaviors and semantics across the framework. Where `Overflow.visible` was used, use `Clip.none`. Where `Overflow.clip` was used, use `Clip.hardEdge`. **Migration guide** [In-depth migration guide available][] Code before migration: ```dart const Stack stack = Stack(overflow: Overflow.visible); const Stack stack = Stack(overflow: Overflow.clip); ``` Code after migration: ```dart const Stack stack = Stack(clipBehavior: Clip.none); const Stack stack = Stack(clipBehavior: Clip.hardEdge); ``` **References** API documentation: * [`Stack`][] * [`Clip`][] Relevant issues: * Resolved [#66030](https://github.com/flutter/flutter/issues/66030) Relevant PRs: * Deprecated in [#66305](https://github.com/flutter/flutter/issues/66305) * Removed in [#98583](https://github.com/flutter/flutter/issues/98583) [In-depth migration guide available]: /release/breaking-changes/clip-behavior [`Stack`]: https://api.flutter.dev/flutter/widgets/Stack-class.html [`Clip`]: https://api.flutter.dev/flutter/dart-ui/Clip.html --- ### `UpdateLiveRegionEvent` Supported by Flutter Fix: no The `SemanticsEvent` `UpdateLiveRegionEvent`, was first deprecated in v1.12, and then extended in v1.26. This was never implemented by the framework, and any references should be removed. **References** API documentation: * [`SemanticsEvent`][] Relevant PRs: * Deprecated in [#45940](https://github.com/flutter/flutter/issues/45940) * Removed in [#98615](https://github.com/flutter/flutter/issues/98615) [`SemanticsEvent`]: https://api.flutter.dev/flutter/semantics/SemanticsEvent-class.html --- ### `RenderObjectElement` methods Supported by Flutter Fix: yes The following `RenderObjectElement` methods were deprecated in v1.21. - `insertChildRenderObject` - `moveChildRenderObject` - `removeChildRenderObject` These methods are replaced, respectively, by: - `insertRenderObjectChild` - `moveRenderObjectChild` - `removeRenderObjectChild` These changes were made as a soft breaking deprecation in order to change the function signature. **Migration guide** Code before migration: ```dart element.insertChildRenderObject(child, slot); element.moveChildRenderObject(child, slot); element.removeChildRenderObject(child); ``` Code after migration: ```dart element.insertRenderObjectChild(child, slot); element.moveRenderObjectChild(child, oldSlot, newSlot); element.removeRenderObjectChild(child, slot); ``` **References** API documentation: * [`RenderObjectElement`][] Relevant issues: * [Issue 63269](https://github.com/flutter/flutter/issues/63269) Relevant PRs: * Deprecated in [#64254](https://github.com/flutter/flutter/issues/64254) * Removed in [#98616](https://github.com/flutter/flutter/issues/98616) [`RenderObjectElement`]: https://api.flutter.dev/flutter/widgets/RenderObjectElement-class.html --- ## Timeline In stable release: 3.0.0
