onComponentDidCatch property

(dynamic Function(dynamic error, ReactErrorInfo info)?) onComponentDidCatch
getter/setter pair

An optional callback that will be called with an Error (or Exception) and errorInfo containing information about which component in the tree threw when the componentDidCatch lifecycle method is called.

This callback can be used to log component errors like so:

(ErrorBoundary()
  ..onComponentDidCatch = (error, errorInfo) {
    // It is up to you to implement the service / thing that calls the service.
    logComponentStackToAService(error, errorInfo);
  }
)(
  // The rest of your component tree
)
