I've solved it by these steps..

1. Remove installed package react-native-material-dropdown

   yarn remove react-native-material-dropdown

2. Install new packages react-native-material-dropdown-v2 and react-native-paper

   yarn add react-native-material-dropdown-v2 react-native-paper

3. Swap react-native-material-dropdown to react-native-material-dropdown-v2 in your code

   eg import { Dropdown } from 'react-native-material-dropdown' to import { Dropdown } from 'react-native-material-dropdown-v2'
