prefer-define-hero-tag
Warns when a Widget has an unset heroTag.
When heroTag is not set, the default value is used. Having two or more widgets with the same heroTag will result in an error.
Example
❌ Bad:
// LINT: This widget is missing the 'heroTag' argument. Try adding it.
FloatingActionButton(
onPressed: () => context.read<CounterCubit>().increment(),
child: const Icon(Icons.add),
);
✅ Good:
FloatingActionButton(
onPressed: () => context.read<CounterCubit>().increment(),
child: const Icon(Icons.add),
heroTag: 'increment_heroTag',
);
