hasError property

bool hasError

Whether a component within the tree that the ErrorBoundary is wrapping around threw an error.

• When true, and ErrorBoundaryProps.fallbackUIRenderer is set, the return value of that callback will be rendered instead.

• When true, and ErrorBoundaryProps.fallbackUIRenderer is not set, the ErrorBoundary will re-mount the tree to attempt to automatically recover from the error.

  If an identical error is thrown from an identical component within the tree consecutively more frequently than ErrorBoundaryProps.identicalErrorFrequencyTolerance, a static copy of the render tree's HTML that was captured at the time of the error will be rendered. See: ErrorBoundaryProps.onComponentIsUnrecoverable for more information about this scenario.

Implementation
