isDirty property

ReadonlySignal<bool> get isDirty

Reactive signal indicating whether user actions have modified the initial value.

Declared as a ReadonlySignal so that composite controls (BloomFieldArray, BloomFormGroup) can satisfy it with a computed that aggregates their children's dirty state. Leaf controls such as BloomFormField narrow it to a writable Signal, which is a valid covariant override.

Implementation

ReadonlySignal<bool> get isDirty;
