Deprecated API removed after v3.13

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.

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

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.

Migration guide

Code before migration:

Chip(useDeleteButtonTooltip: false);
InputChip(useDeleteButtonTooltip: true);
RawChip rawChip = RawChip();
rawChip.useDeleteButtonTooltip;

Code after migration:

Chip(deleteButtonTooltipMessage: '');
InputChip();
RawChip rawChip = RawChip();
rawChip.deleteButtonTooltipMessage;

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:

class MyButtonClass extends StatelessWidget with MaterialButtonWithIconMixin {
  // ...
}

Code after migration:

class MyButtonClass extends StatelessWidget {
  // ...
}

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:

await PlatformsViewsService.synchronizeToNativeViewHierarchy(false);

Code after migration:

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:

TextSelectionOverlay.fadeDuration;

Code after migration:

SelectionOverlay.fadeDuration;

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:

MaterialApp(
  scrollBehavior: MaterialScrollBehavior(
    androidOverscrollIndicator: AndroidOverscrollIndicator.glow,
  ),
  //...
);
​
MaterialApp(
  scrollBehavior: ScrollBehavior(
    androidOverscrollIndicator: AndroidOverscrollIndicator.glow,
  ),
  //...
);
​
MaterialApp(
  theme: Theme.light().copyWith(
    androidOverscrollIndicator: AndroidOverscrollIndicator.glow,
  ),
  //...
);

Code after migration:

MaterialApp(
  theme: Theme.light().copyWith(
    // defaults to true and stretching indicator,
    // false results in glowing indicator
    useMaterial3: false,
  ),
  //...
);

Migration guide

  tester.binding.window.textScaleFactorTestValue = 42;
  addTearDown(tester.binding.window.clearTextScaleFactorTestValue);
  // ...
});

Code after migration:

testWidgets('My test', (WidgetTester tester) aysnc {
  // For all instances, replace window with platformDispatcher
