TypeError: undefined is not an object (evaluating ‘_reactNative.Animated.Text.propTypes.style’)

I solved this by,

• Commenting itemTextStyle: Text.propTypes.style in
  ..\node_modules\react-native-material-dropdown\src\components\dropdown
  file.

• And remove Animated in Animated.Text.propTypes.style in

  affix/index

  helper/index

  label/index

  of react-native-material-textfield.

• And added import { Animated, Text} from 'react-native'; in each of
  above three files.
