Deprecated API removed after v3.10
Summary
#In accordance with Flutter's Deprecation Policy, deprecated APIs that reached end of life after the 3.10 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.
Changes
#This section lists the deprecations, listed by the package and affected class.
ThemeData.fixTextFieldOutlineLabel
#Package: flutter Supported by Flutter Fix: yes
ThemeData.fixTextFieldOutlineLabel
was deprecated in v2.5.
References to this property can be removed.
The fixTextFieldOutlineLabel
was a temporary migration flag that allowed users
to gracefully migrate to a new behavior rather than experiencing a hard break.
Before deprecating, this property was transitioned to the new default from the
fix to the label for text fields.
Migration guide
Code before migration:
var themeData = ThemeData(
fixTextFieldOutlineLabel: true,
);
Code after migration:
var themeData = ThemeData(
);

OverscrollIndicatorNotification.disallowGlow
#Package: flutter Supported by Flutter Fix: yes
OverscrollIndicatorNotification.disallowGlow
was deprecated in v2.5.
The replacement is the disallowIndicator
method.
The disallowIndicator
was created as a replacement for the original method
with the introduction of the StretchingOverscrollIndicator
. Previously,
the GlowingOverscrollIndicator
was the only kind to dispatch
OverscrollIndicatorNotification
s, and so the method was updated to better
reflect multiple kinds of indicators.
Migration guide
Code before migration:
bool _handleOverscrollIndicatorNotification(OverscrollIndicatorNotification notification) {
notification.disallowGlow();
return false;
}
Code after migration:
bool _handleOverscrollIndicatorNotification(OverscrollIndicatorNotification notification) {
notification.disallowIndicator();
return false;
}

ColorScheme primaryVariant & secondaryVariant
#Package: flutter Supported by Flutter Fix: yes
ColorScheme.primaryVariant
and ColorScheme.secondaryVariant
were deprecated
in v2.6. The replacements are the ColorScheme.primaryContainer
and
ColorScheme.secondaryContainer
, respectively.
These changes were made to align with the updated Material Design specification
for ColorScheme
. The updates to ColorScheme
are covered more extensively in
the ColorScheme for Material 3 design document.
Migration guide
Code before migration:
var colorScheme = ColorScheme(
primaryVariant: Colors.blue,
secondaryVariant: Colors.amber,
);
var primaryColor = colorScheme.primaryVariant;
var secondaryColor = colorScheme.secondaryVariant;
Code after migration:
var colorScheme = ColorScheme(
primaryContainer: Colors.blue,
secondaryContainer: Colors.amber,
);
var primaryColor = colorScheme.primaryContainer;
var secondaryColor = colorScheme.secondaryContainer;

ThemeData.primaryColorBrightness
#Package: flutter Supported by Flutter Fix: yes
ThemeData.primaryColorBrightness
was deprecated in v2.6, and has not been used
by the framework since then. References should be removed. The Brightness
is
now extrapolated from the ThemeData.primaryColor
if ThemeData.brightness
has
not been explicitly provided.
This change was made as part of the update to Theme
to match new Material
Design guidelines. The overall update to the theming system, including the
removal of primaryColorBrightness
is discussed more extensively in the
Material Theme System Updates design document.
Migration guide
Code before migration:
var themeData = ThemeData(
primaryColorBrightness: Brightness.dark,
);
Code after migration:
var themeData = ThemeData(
);

RawScrollbar & subclasses updates
#Package: flutter Supported by Flutter Fix: yes
The isAlwaysShown
property of RawScrollbar
, Scrollbar
,
ScrollbarThemeData
and CupertinoScrollbar
was deprecated in v2.9. The
replacement in all cases is thumbVisibility
.
This change was made since isAlwaysShown
always referred to the scrollbar
thumb. With the addition of a scrollbar track, and varying configurations for
its visibility in response to mouse hovering and dragging, we renamed this
property for a clearer API.
Additionally, Scrollbar.hoverThickness
was also deprecated in v2.9. Its
replacement is the MaterialStateProperty
ScrollbarThemeData.thickness
.
This change was made to allow the thickness of a Scrollbar
to respond to all
kind of states, including and beyond just hovering. The use of
MaterialStateProperties
also matches the convention in the material library of
configuring widgets based on their state, rather than enumerating properties for
every permutation of interactive states.
Migration guide
Code before migration:
var rawScrollbar = RawScrollbar(
isAlwaysShown: true,
);
var scrollbar = Scrollbar(
isAlwaysShown: true,
hoverThickness: 15.0,
);
var cupertinoScrollbar = CupertinoScrollbar(
isAlwaysShown: true,
);
var scrollbarThemeData = ScrollbarThemeData(
isAlwaysShown: true,
);
Code after migration:
var rawScrollbar = RawScrollbar(
thumbVisibility: true,
);
var scrollbar = Scrollbar(
thumbVisibility: true,
);
var cupertinoScrollbar = CupertinoScrollbar(
thumbVisibility: true,
);
var scrollbarThemeData = ScrollbarThemeData(
thumbVisibility: true,
thickness: MaterialStateProperty.resolveWith((Set<MaterialState> states) {
return states.contains(MaterialState.hovered) ? null : 15.0;
}),
);

AnimationSheetBuilder display & sheetSize
#Package: flutter_test Supported by Flutter Fix: yes
The display
and sheetSize
methods of AnimationSheetBuilder
were deprecated
in v2.3. The replacement is the collate
method.
AnimationSheetBuilder
's output step previously required these two methods to
be called, but is now streamlined through a single call to collate
.
The collate
function directly puts the images together and asynchronously
returns an image. It requires less boilerplate, and outputs smaller images
without any compromise to quality.
Migration guide

Code before migration:
final AnimationSheetBuilder animationSheet = AnimationSheetBuilder(
frameSize: const Size(40, 40)
);
await tester.pumpFrames(animationSheet.record(
const Directionality(
textDirection: TextDirection.ltr,
child: Padding(
padding: EdgeInsets.all(4),
child: CircularProgressIndicator(),
),
),
), const Duration(seconds: 2));
tester.binding.setSurfaceSize(animationSheet.sheetSize());
final Widget display = await animationSheet.display();
await tester.pumpWidget(display);
await expectLater(
find.byWidget(display),
matchesGoldenFile('material.circular_progress_indicator.indeterminate.png'),
);

flutter_test timeout logic
#Package: flutter_test Supported by Flutter Fix: no
The following APIs related to timeout logic in tests were deprecated
in v2.6. There are no replacements, and references should be removed, except for
the initialTimeout
parameter of testWidgets
, which is replaced by using
timeout
.
TestWidgetsFlutterBinding.addTime
TestWidgetsFlutterBinding.runAsync
method -additionalTime
parameterTestWidgetsFlutterBinding.runTest
method -timeout
parameterAutomatedTestWidgetsFlutterBinding.runTest
method -timeout
parameterLiveTestWidgetsFlutterBinding.runTest
method -timeout
parametertestWidgets
method -initialTime
parameter
These were found to cause flakiness in testing, and were not in use by tested customers.
Since being deprecated, use of these parameters have had no effect on tests, so removing references should have no effect on existing code bases.
Migration guide
Code before migration:
testWidgets('Test', (_) {}, initialTimeout: Duration(seconds: 5));
Code after migration:
testWidgets('Test', (_) {}, timeout: Timeout(Duration(seconds: 5)));
