_checkPermissions = async () => {
    try {
      const { status } = await Permission.askAsync(Permission.CAMERA);
      this.setState({ camera: status });
      const { statusRoll } = await Permission.askAsync(Permission.CAMERA_ROLL);

        mediaTypes: "Images",
        allowsEditing: true,
        quality: 1
      });

      if (!result.cancelled) {
        this.setState({
          image: result.uri
        });
      } else {
        console.log("cancel");

     // console.log(err);
    }
  };

Answer 1

to me what solved it was importing the permissions and imagePicker like this:

import * as Permissions from 'expo-permissions';
import * as ImagePicker from 'expo-image-picker';

instead of this:

import Permissions from 'expo-permissions';
import ImagePicker from 'expo-image-picker';

And that's basically because there is no default export
