# Deprecated API removed after v3.13 > 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 3.13 stable release have been removed. All affected APIs have been compiled into this primary source to aid in migration. To further aid your migration, check out this [quick reference sheet][]. [Deprecation Policy]: https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md#deprecations [quick reference sheet]: /go/deprecations-removed-after-3-13 ## Changes This section lists the deprecations by the package and affected class. ### Chip classes' useDeleteButtonTooltip Package: flutter Supported by Flutter Fix: yes The `useDeleteButtonTooltip` property of the following classes was deprecated in v2.10: * `DeletableChipAttributes` * `Chip` * `RawChip` * `InputChip` `deleteButtonTooltipMessage` replaces `useDeleteButtonTooltip`. This change simplified the API, as providing an empty String to `deleteButtonTooltipMessage` achieves the same result as setting the original property `useDeleteButtonTooltip` to false. When `deleteButtonTooltipMessage` is unset, the `MaterialLocalizations.deleteButtonTooltip` is used by default. The [Deprecate `useDeleteButtonTooltip` for Chips][] design document covers this update to chips and tooltips in greater depth. To learn more, check out the [chips and tooltips migration guide][]. [Deprecate `useDeleteButtonTooltip` for Chips]: https://docs.google.com/document/d/1wc9ot7T2E7hJubYxEWMX230a79wYSiFey4BHxnEzHtw/edit?usp=sharing&resourcekey=0-Bo7KPqEtkWgZcSuRCqwQ5w [chips and tooltips migration guide]: /release/breaking-changes/chip-usedeletebuttontooltip-migration **Migration guide** Code before migration: ```dart Chip(useDeleteButtonTooltip: false); InputChip(useDeleteButtonTooltip: true); RawChip rawChip = RawChip(); rawChip.useDeleteButtonTooltip; ``` Code after migration: ```dart Chip(deleteButtonTooltipMessage: ''); InputChip(); RawChip rawChip = RawChip(); rawChip.deleteButtonTooltipMessage; ``` **References** API documentation: * [`DeletableChipAttributes`][] * [`Chip`][] * [`RawChip`][] * [`InputChip`][] * [`MaterialLocalizations.deleteButtonTooltip`][] Relevant PRs: * Deprecated in [#96174][] * Removed in [#134486][] [`DeletableChipAttributes`]: https://api.flutter.dev/flutter/material/DeletableChipAttributes-class.html [`Chip`]: https://api.flutter.dev/flutter/material/Chip-class.html [`RawChip`]: https://api.flutter.dev/flutter/material/RawChip-class.html [`InputChip`]: https://api.flutter.dev/flutter/material/InputChip-class.html [`MaterialLocalizations.deleteButtonTooltip`]: https://api.flutter.dev/flutter/material/MaterialLocalizations/deleteButtonTooltip.html [#96174]: https://github.com/flutter/flutter/pull/96174 [#134486]: https://github.com/flutter/flutter/pull/134486 --- ### MaterialButtonWithIconMixin Package: flutter Supported by Flutter Fix: no The `MaterialButtonWithIconMixin` property was deprecated in v2.11. With the introduction of new button classes `TextButton`, `OutlinedButton` and `ElevatedButton`, this mixin is no longer used. An earlier release removed old button classes that used this mixin. As a result, this mixin no longer affects any classes that might mix it in. **Migration guide** Code before migration: ```dart class MyButtonClass extends StatelessWidget with MaterialButtonWithIconMixin { // ... } ``` Code after migration: ```dart class MyButtonClass extends StatelessWidget { // ... } ``` **References** Relevant PRs: * Deprecated in [#99088][] * Removed in [#133173][] [#99088]: https://github.com/flutter/flutter/pull/99088 [#133173]: https://github.com/flutter/flutter/pull/133173 --- ### PlatformsViewsService.synchronizeToNativeViewHierarchy Package: flutter Supported by Flutter Fix: no The static method `synchronizeToNativeViewHierarchy` of `PlatformsViewsService` was deprecated in v2.11. During the deprecation period, the method was a no-op function as it was no longer required to call for performance improvements. References to the method should be removed and won't impact the application. **Migration guide** Code before migration: ```dart await PlatformsViewsService.synchronizeToNativeViewHierarchy(false); ```` Code after migration: ```dart ``` **References** API documentation: * [`PlatformViewsService`][] Relevant PRs: * Deprecated in [#100990][] * Removed in [#133175][] [`PlatformViewsService`]: https://api.flutter.dev/flutter/services/PlatformViewsService-class.html [#100990]: https://github.com/flutter/flutter/pull/100990 [#133175]: https://github.com/flutter/flutter/pull/133175 --- ### TextSelectionOverlay.fadeDuration Package: flutter Supported by Flutter Fix: yes The static `fadeDuration` property of `TextSelectionOverlay` was deprecated in v2.12. The `SelectionOverlay.fadeDuration` property replaces `TextSelectionOverlay.fadeDuration`. With the `TextSelectionOverlay` refactor, `SelectionOverlay` was added as a more generic widget without the specific dependency on `RenderEditable`. **Migration guide** Code before migration: ```dart TextSelectionOverlay.fadeDuration; ``` Code after migration: ```dart SelectionOverlay.fadeDuration; ``` **References** API documentation: * [`TextSelectionOverlay`][] * [`SelectionOverlay`][] Relevant PRs: * Deprecated in [#100381][] * Removed in [#134485][] [`TextSelectionOverlay`]: https://api.flutter.dev/flutter/widgets/TextSelectionOverlay-class.html [`SelectionOverlay`]: https://api.flutter.dev/flutter/widgets/SelectionOverlay-class.html [#100381]: https://github.com/flutter/flutter/pull/100381 [#134485]: https://github.com/flutter/flutter/pull/134485 --- ### androidOverscrollIndicator Package: flutter Supported by Flutter Fix: no The `androidOverscrollIndicator` property of the following classes was deprecated in v2.13: * `ScrollBehavior` * `MaterialScrollBehavior` * `ThemeData` This flag was introduced to allow users to configure scrolling widgets to use the `GlowingOverscrollIndicator` or the `StretchingOvercrollIndicator`. It was deprecated in favor of the `ThemeData.useMaterial3` flag as the framework introduced more support for Material 3-styled widgets. Since `ThemeData.useMaterial3` is `true` by default, the `StretchingOverscrollIndicator` is applied by default. Setting this value to `false` will apply a `GlowingOverscrollIndicator` instead. Alternatively, the `buildOverscrollIndicator` method of `ScrollBehavior` or `MaterialScrollBehavior` can be overridden to further alter the appearance of overscroll indicators. **Migration guide** Code before migration: ```dart MaterialApp( scrollBehavior: MaterialScrollBehavior( androidOverscrollIndicator: AndroidOverscrollIndicator.glow, ), //... ); MaterialApp( scrollBehavior: ScrollBehavior( androidOverscrollIndicator: AndroidOverscrollIndicator.glow, ), //... ); MaterialApp( theme: Theme.light().copyWith( androidOverscrollIndicator: AndroidOverscrollIndicator.glow, ), //... ); ``` Code after migration: ```dart MaterialApp( theme: Theme.light().copyWith( // defaults to true and stretching indicator, // false results in glowing indicator useMaterial3: false, ), //... ); ``` **References** API documentation: * [`ScrollBehavior`][] * [`MaterialScrollBehavior`][] * [`ThemeData`][] * [`GlowingOverscrollIndicator`][] * [`StretchingOverscrollIndicator`][] Relevant PRs: * Deprecated in [#100234][] * Removed in [#133181][] [`ScrollBehavior`]: https://api.flutter.dev/flutter/widgets/ScrollBehavior-class.html [`MaterialScrollBehavior`]: https://api.flutter.dev/flutter/material/MaterialScrollBehavior-class.html [`ThemeData`]: https://api.flutter.dev/flutter/material/ThemeData-class.html [`GlowingOverscrollIndicator`]: https://api.flutter.dev/flutter/widgets/GlowingOverscrollIndicator-class.html [`StretchingOverscrollIndicator`]: https://api.flutter.dev/flutter/widgets/StretchingOverscrollIndicator-class.html [#100234]: https://github.com/flutter/flutter/pull/100234 [#133181]: https://github.com/flutter/flutter/pull/133181 --- ### Updates to ImageProvider and PaintingBinding Package: flutter Supported by Flutter Fix: no The `instantiateImageCodec` method of `PaintingBinding`, as well as the `load` method of `ImageProvider` and the associated `DecoderCallback` were all deprecated in v2.13. The respective replacements are: | Deprecated Method | Current Method | |-----------------------------------------|---------------------------------------------------| | `PaintingBinding.instantiateImageCodec` | `PaintingBinding.instantiateImageCodecFromBuffer` | | `ImageProvider.load` | `ImageProvider.loadBuffer` | | `DecoderCallback` | `DecoderBufferCallback` | This change enabled faster performance in image loading by using a buffer. **Migration guide** Code before migration: ```dart PaintingBinding.instance.instantiateImageCodec ``` Code after migration: ```dart PaintingBinding.instance.instantiateImageCodecFromBuffer ``` **References** API documentation: * [`PaintingBinding`][] * [`ImageProvider`][] * [`DecoderBufferCallback`][] Relevant PRs: * Deprecated in [#103496][] * Removed in [#132679][] [`PaintingBinding`]: https://api.flutter.dev/flutter/painting/PaintingBinding-mixin.html [`ImageProvider`]: https://api.flutter.dev/flutter/painting/ImageProvider-class.html [`DecoderBufferCallback`]: https://api.flutter.dev/flutter/painting/DecoderBufferCallback.html [#103496]: https://github.com/flutter/flutter/pull/103496 [#132679]: https://github.com/flutter/flutter/pull/132679 --- ### TestWindow properties Package: flutter_test Supported by Flutter Fix: no To prepare for multi-window support, many deprecated properties of `TestWindow` have been removed. While `TestWindow` has been deprecated, it does not qualify for removal at this time. Migrating the expired properties now will help in migrating from `TestWindow`. The following properties were removed: * `localeTestValue` * `clearLocaleTestValue` * `localesTestValue` * `clearLocalesTestValue` * `initialLifecycleStateTestValue` * `textScaleFactorTestValue` * `clearTextScaleFactorTestValue` * `platformBrightnessTestValue` * `clearPlatformBrightnessTestValue` * `alwaysUse24HourFormatTestValue` * `clearAlwaysUse24HourTestValue` * `brieflyShowPasswordTestValue` * `defaultRouteNameTestValue` * `clearDefaultRouteNameTestValue` * `semanticsEnabledTestValue` * `clearSemanticsEnabledTestValue` * `accessibilityFeaturesTestValue` * `clearAccessibilityFeaturesTestValue` To learn more about this `TestWindow` update, check out [`TestWindow` migration guide][].
