This section lists the deprecations by the package and affected class.

Button styleFrom properties

#

Package: flutter Supported by Flutter Fix: yes

The TextButton, ElevatedButton and OutlinedButton widgets all have a static styleFrom method for generating the ButtonStyle. The following color properties of this method for each class were deprecated in v3.1:

  • TextButton.styleFrom
    • primary
    • onSurface
  • ElevatedButton.styleFrom
    • primary
    • onPrimary
    • onSurface
  • OutlinedButton.styleFrom
    • primary
    • onSurface

These changes better aligned the API with updated Material Design specifications. The changes also provided more clarity in how the colors would be applied to the buttons, by replacing these properties with backgroundColor, foregroundColor, and disabledForegroundColor.

Migration guide

Code before migration:

dart
TextButton.styleFrom(
  primary: Colors.red,
  onSurface: Colors.black,
);
ElevatedButton.styleFrom(
  primary: Colors.red,
  onPrimary: Colors.blue,
  onSurface: Colors.black,
);
OutlinedButton.styleFrom(
  primary: Colors.red,
  onSurface: Colors.black,
);

Code after migration:

dart
TextButton.styleFrom(
  foregroundColor: Colors.red,
  disabledForegroundColor: Colors.black,
);
ElevatedButton.styleFrom(
  backgroundColor: Colors.red,
  foregroundColor: Colors.blue,
  disabledForegroundColor: Colors.black,
);
OutlinedButton.styleFrom(
  foregroundColor: Colors.red,
  disabledForegroundColor: Colors.black,
);

ThemeData.selectedRowColor

#

Package: flutter Supported by Flutter Fix: yes

The selectedRowColor property of ThemeData was deprecated in v3.1.

The property was no longer used by the framework, as widgets using it migrated to other component themes or no longer required it in the updated specification for Material Design.

Migration guide

Code before migration:

dart
ThemeData(
  // ...
  selectedRowColor: Colors.pink, // Would have no effect.  
);

Code after migration:

dart
ThemeData(
  // ...
  // Remove uses.  
);

#

Package: flutter Supported by Flutter Fix: yes

The focusScopeNode property of NavigatorState was deprecated in v3.1.

This change was made to resolve several issues stemming around the FocusScopeNode introduced by the Navigator. Instead, the FocusScope was moved to enclose the topmost Navigator in a WidgetsApp. NavigatorState was changed to contain its own FocusNode, from where it can refer to its FocusNode.enclosingScope to access the correct FocusScopeNode.

Migration guide

Code before migration:

dart
Navigator.of(context).focusScopeNode;

Code after migration:

dart
Navigator.of(context).focusNode.enclosingScope!;

PlatformMenuBar.body

#

Package: flutter Supported by Flutter Fix: yes

The body property of PlatformMenuBar was deprecated in v3.1.

This change was made to align PlatformMenuBar with other widgets in the framework, renaming it to child.

Migration guide

Code before migration:

dart
PlatformMenuBar(
  body: myWidget,
);

Code after migration:

dart
PlatformMenuBar(
  child: myWidget,
);

The previously announced deprecations for TextTheme, WidgetInspectorService, and WidgetInspectorServiceExtensions were not removed during this cycle. The WidgetInspectorService and WidgetInspectorServiceExtensions deprecation on setPubRootDirectories has been extended another year to allow IDEs and other customer to migrate. Expect the TextTheme deprecations to be removed in the next cycle, which will be announced again when it comes.
