migration guide policy.
All affected APIs have been compiled into this
primary source to aid in migration. A
quick reference sheet is available as well.
A design document and article are available
for more context on Flutter’s deprecation policy.

Supported by fix tool: Yes | https://docs.flutter.dev/release/breaking-changes/1-22-deprecations/index.html |
ac291c931a60-18 | Generic methods for BuildContext
Supported by fix tool: Yes
Several methods in BuildContext were using Type to search for ancestors. Most of those methods
implied a cast at call site because their return type was a parent type. Moreover the type provided
was not checked at analysis time even if the type is actually constrained. Making these methods
generics improves type safety and requires less code.
These method changes affect the BuildContext, Element, and StatefulElement classes. The
TypeMatcher class was also removed.

WidgetsBinding.deferFirstFrameReport & WidgetsBinding.allowFirstFrameReport
Supported by fix tool: Yes
The deferFirstFrameReport and allowFirstFrameReport methods of WidgetsBinding were deprecated
and removed in order to provide the option to delay rendering the first frame. This is useful for
widgets that need to obtain initialization information asynchronously and while they are waiting for
that information no frame should render as that would take down the splash screen pre-maturely.
The deferFirstFrame and allowFirstFrame methods should be used respectively instead.

WaitUntilNoTransientCallbacks, WaitUntilNoPendingFrame, & WaitUntilFirstFrameRasterized
Supported by fix tool: No
The WaitUntilNoTransientCallbacks, WaitUntilNoPendingFrame, and WaitUntilFirstFrameRasterized
methods from the flutter_driver packages were deprecated and removed in order to provide a more
composable waitForCondition API that can be used to compose conditions that the client would like
to wait for.

Supported by Flutter Fix: yes | https://docs.flutter.dev/release/breaking-changes/2-10-deprecations/index.html |
df2a873730be-6 | VelocityTracker constructor
Supported by Flutter Fix: yes
The default constructor for VelocityTrackerwas 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.

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.

RenderEditable.onSelectionChanged and TextSelectionDelegate.textEditingValue

packageRoot in dart:core, dart:isolate, and package:platform
The following APIs have been removed:
Platform.packageRoot in dart:core
Isolate.packageRoot in dart:isolate
Platform.packageRoot in package:platform
These APIs were marked deprecated in Dart 2.0, and did not
work correctly in any Dart 2.x release.
Migration guide
These packageRoot APIs have been replaced by a new set of packageConfig APIs,
which you should migrate to. | https://docs.flutter.dev/release/breaking-changes/2-5-deprecations/index.html |
abfc3fc3478f-17 | Platform.packageConfig in dart:core
Isolate.packageConfig in dart:isolate
Platform.packageConfig in package:platform
If you are using the package:platform package, note that regardless of whether
you are using the packageRoot API or not, older versions of that package are
not compatible with Dart 2.16 and later, as they depend on the now removed
packageRoot API. You may see an error like this when attempting to run your
app:
To resolve that, upgrade to version 3.1.0 or later of package:platform by
upgrading the constraint in your pubspec.yaml file:
dependencies
platform
^3.1.0
