Description
Steps to Reproduce
If you create an AppBarTheme where you define properties for its iconTheme and actionsIconTheme, for example
const myAppBarTheme = AppBarTheme(
iconTheme: IconThemeData(color: Colors.deepOrange, size: 32.0),
actionsIconTheme: IconThemeData(color: Colors.yellow, size: 32.0),
);and create a ThemeData where it is assigned to appBarTheme and useMaterial3 is true, and use it as your MaterialApp.theme. The assigned AppBarTheme colors are not respected on latest Channel master, 3.1.0-0.0.pre.1560, but on Flutter stable 3.0.4 it works OK.
Is this a regression? Looks so to me.
Expected results (on stable 3.0.4)
On current Flutter Stable channel this works OK.
This can be tested and verified with the sample code in this DartPad as well:
https://dartpad.dev/?id=946d29aa48e8ec3446281acaab61e4c5
| M2 Mode (Stable) = OK | M3 Mode (Stable) = OK |
|---|---|
 |
 |
Actual results (on master channel)
| M2 Mode (Master) = OK | M3 Mode (Master) = FAIL |
|---|---|
 |
 |
| OK | Expected AppBarTheme's icon colors to be used |
The icon sizes in the AppBarTheme are respected, but the colors are overridden by the AppBar's M3 default icon colors. Presumably it should be possible to control the icon colors via the AppBarTheme as before also when using Material3.
