[tool.flet.android]
min_sdk_version = 24

[tool.flet.flutter.pubspec.dependency_overrides]
webview_flutter_android = "4.10.1"

And now my builds work again. Thank to you for this PR and information about the SDK, cause the error message I was getting during the build made no sense to me

[SamYuan1990]

@SamYuan1990 I was able to do the same thing as your template PR by just adding to my pyproject.toml

[tool.flet.android]
min_sdk_version = 24

[tool.flet.flutter.pubspec.dependency_overrides]
webview_flutter_android = "4.10.1"

And now my builds work again. Thank to you for this PR and information about the SDK, cause the error message I was getting during the build made no sense to me

thanks to let me know there is tool.flet.flutter.pubspec.dependency_overrides

[djefferson-saintilus]

[tool.flet.android]
min_sdk_version = 24

[tool.flet.flutter.pubspec.dependency_overrides]
webview_flutter_android = "4.10.1"

[Progressing-Llama]

I was facing the same.
By changing pyproject.toml as above my workflow is working now. Thanks!
