state

componentDidMount

• componentDidMount(): void

  Called immediately after a component is mounted. Setting state here will trigger re-rendering.

  Returns void

componentWillUnmount

• componentWillUnmount(): void

  Called immediately before a component is destroyed. Perform any necessary cleanup in this method, such as cancelled network requests, or cleaning up any DOM elements created in componentDidMount.

  Returns void

openDropdown

• openDropdown(): void

  Returns void

render

• render(): ReactNode

  Returns ReactNode

UNSAFE_componentWillReceiveProps

• UNSAFE_componentWillReceiveProps(nextProps: MarkerProps): void

  Called when the component may be receiving new props. React may call this even if props have not changed, so be sure to compare new and existing props if you only want to handle changes.

  Calling Component.setState generally does not trigger this method.

  This method will not stop working in React 17.

  Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.

  Parameters

  • nextProps: MarkerProps

  Returns void

  Deprecated

  16.3, use static getDerivedStateFromProps instead
