TypeError: null is not an object (evaluating '_reactNative.NativeModules.DialogAndroid.show'

Hello I’m getting that error and I don’t understand why ?

Here is my code

_selectForm = async () => {
    try {
      const { selectedItem } = await DialogAndroid.showPicker('Pick a form', null, {
        items: [
          { label:'12 Months', id:'12-months' },
          { label:'16 Months', id:'16-months' },
          { label:'20 Months', id:'20-months' }
        ]
      });
      if (selectedItem) {
        // when negative button is clicked, selectedItem is not present, so it doesn't get here
        console.log('You selected item:', selectedItem);
        this.props.navigation.navigate("CollectingDataScreen", {
          form: selectedItem
        });
      }
    } catch(e) {
      console.log("DIALOG ANDROID EROOR ... ", e);
    }
  }

And after installing, the version from package.json is "react-native-dialogs": "^1.0.4"

this error is caused by the fact that the native module is not correctly linked; follow https://github.com/aakashns/react-native-dialogs#manual-linking or if you’re on RN0.60 or newer, compiling should just work because of autolinking

Look, I’m having this error:

And in this case, my code is:

dialog = () => {
    const options = [
        { label: 'Most Votes (Likes + Dislikes)', value: 'thumbs' },
        { label: 'Most Likes', value: 'thumbs-up' },
        { label: 'Most Dislikes', value: 'thumbs-down' },
        { label: 'Recent Activity', value: 'recent' },
        { label: 'Most Comments', value: 'comments' },
        { label: 'Most Helpful Comments', value: 'helpful-comments' },
        { label: 'Cancel', value: 'cancel' }
      ];

      const { selectedItem } = await DialogAndroid.showPicker('im a title', null, {
        items: options.slice(0, options.length - 1), // no cancel button
        idKey: 'value',
        positiveText: null,
        negativeText: 'Cancel'
      });

      if (selectedItem) {
        // when negative button is clicked, selectedItem is not present, so it doesn't get here
        console.log('You picked:', selectedItem);
      }
}

<TouchableOpacity style={styles.lastItem} onPress={this.dialog}>
    <Text style={styles.name}>{this.state.notificationSelected}</Text>
</TouchableOpacity>
