dispatch(
  AlertActions.alert({
    title: 'foo',
    message: 'bar',
    buttons: [
      {
        text: 'baz',
        onPressAction: { type: 'BAZ', payload: { qux: 'qux' } },
      },
    ],
    options: {
      // below are only for Android
      cancelable: true,
      onDismissAction: { type: 'QUX', payload: { qux: 'qux' } },
    },
    type: '',
  }),
)
