# AssertionError: '!_debugAllowCreation' is not true in release mode

- **ID:** `flutter/release-mode-debug-assert`
- **Domain:** flutter
- **Category:** assertion_error
- **Verification:** ai_generated
- **Fix Rate:** 72%

## Root Cause

A debug-only assertion that checks widget creation permissions is triggered in release mode because the code path that should be disabled (e.g., a debug overlay or inspector) is still active due to a misconfigured build flag or leftover debug code.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| Flutter 3.13.0 | active | — | — |
| Flutter 3.22.0 | active | — | — |
| Dart 3.1.0 | active | — | — |

## Workarounds

1. **Ensure that debug-specific code (like debugPaintSizeEnabled or custom debug overlays) is wrapped in 'assert(() { ... }());' or conditionally compiled with 'kReleaseMode'. Example:
  if (kDebugMode) {
    // debug-only widget creation
  }** (80% success)
   ```

   ```
2. **Run 'flutter clean' and rebuild with 'flutter build apk --release' to ensure no stale debug artifacts remain.** (75% success)

3. **Check for any third-party packages that may inject debug widgets in release mode; update them or exclude debug features via package configuration.** (70% success)

## Dead Ends

- **Add '--debug' flag to the build command to avoid release mode** — The error occurs in release mode; using debug mode bypasses the issue but doesn't solve the root cause for production builds. (70% fail)
- **Remove all assert() statements from the codebase** — Assertions are stripped in release mode by default; the error is from Flutter's internal assertions, not user code. (90% fail)
- **Set '--no-sound-null-safety' to suppress the assertion** — Null safety is unrelated; the assertion is about widget creation permissions, not null checks. (80% fail)
