Root Cause

Freezed code generation failed due to annotation error.

generic

Workarounds

  1. 92% success Ensure class follows freezed pattern: @freezed class Foo with _
  2. 90% success Run: dart run build_runner build --delete-conflicting-outputs

Dead Ends

Common approaches that don't work:

  1. Write data classes manually 68% fail

    Verbose, misses equality/copyWith

  2. Use json_serializable only 72% fail

    Loses union types and freezed features
