Properties

$defaultConsumedProps → Iterable<ConsumedProps>

The default consumed props, taken from the keys generated in the associated UiProps class.

no setter, inherited

$isClassGenerated → bool

Whether this class has been generated.

no setter, inherited

childContextKeys → Iterable<String>

Do not use.

no setter, inherited

consumedProps → Iterable<ConsumedProps>?

Forward all the props from ErrorBoundaryProps to the child RecoverableErrorBoundary by explicitly setting consumedProps to an empty list.

no setter, override

context ↔ dynamic

The context value from the contextType assigned to this component. The value is passed down from the provider of the same contextType. You can reference context in any of the lifecycle methods including the render function.

Do not use.

no setter, inherited

contextType → Context?

The contextType property lets you consume the nearest current value of that context's Provider using context.

no setter, override

displayName → String?

Allows the ReactJS displayName property to be set for debugging purposes.

no setter, inherited

hashCode → int

The hash code for this object.

no setter, inherited

initialState → Map

Invoked once before the Component is mounted. The return value will be used as the initial value of state.
