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.

中文

一个仅限调试的断言检查小部件创建权限，在发布模式下被触发，因为本应禁用的代码路径（例如调试覆盖层或检查器）由于构建标志配置错误或遗留的调试代码仍然处于活动状态。

Workarounds

80% success 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 }

中文步骤

确保调试特定代码（如 debugPaintSizeEnabled 或自定义调试覆盖层）包装在 'assert(() { ... }());' 中或使用 'kReleaseMode' 条件编译。示例：
  if (kDebugMode) {
    // 仅调试的小部件创建
  }

运行 'flutter clean' 并使用 'flutter build apk --release' 重新构建，确保没有残留的调试工件。

检查可能注入调试小部件的第三方包；更新它们或通过包配置排除调试功能。

Dead Ends

Common approaches that don't work:

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