In accordance with Flutter's Deprecation Policy, deprecated APIs that reached end of life after the 3.10 stable release have been removed.
- Who is affected
- Any code still referencing the removed API will fail to compile after upgrading. Code that uses ThemeData.fixTextFieldOutlineLabel, ThemeData, OverscrollIndicatorNotification.disallowGlow and related APIs.
- Practical impact
- Compile errors until migrated; must be addressed before upgrading.
- What action should I take?
- Review the linked source, update affected code and run your test suite before upgrading.

Listed in the official breaking-changes index; title states removal.
An official announcement or migration guide documents an intended behaviour or API change. A verified source change (git diff) shows code changed but does not by itself prove a public API is breaking. AI interpretations are labelled and never used to classify a change.
