the guide i linked you to also explains how to look into that. you can also google that error. the first result on google leads me to this issue RNCAndroidDropdownPicker was not found in the UIManager · Issue #3435 · GeekyAnts/NativeBase · GitHub

so you could try running expo install @react-native-picker/picker
