hop of those help? to me what solved it was importing the permissions and imagePicker like this:
code :
import * as Permissions from 'expo-permissions';
import * as ImagePicker from 'expo-image-picker';
import Permissions from 'expo-permissions';
import ImagePicker from 'expo-image-picker';

should help you out I would like to debug on my mobile/simulator and point it dynamically to API. , Bring the complete module of the expo with:
code :
import * as Expo from 'expo'
"TypeError: undefined is not an object (evaluating '_expo.default.Font')]" facing this error when asynchronous

I think the issue was by ths following , This is my error: , Welcome to Expo!
This code has some problems.
code :
export default
componentWillMount =  async() => {
if (!this.state.isReady) {
  return <ActivityIndicator />
}
import React, { Component } from 'react'
import { ActivityIndicator } from 'react-native'
import { Container } from 'native-base'
import { AppHeader } from '../sections/Header'
import { Font } from 'expo'

export default class Login extends Component {
  static navigationOptions = {
    header: null
  }

  state = {
    isReady: false
  }

  componentWillMount = async() => {
    await Font.loadAsync({
      Roboto: require('native-base/Fonts/Roboto.ttf'),
      Roboto_medium: require('native-base/Fonts/Roboto_medium.ttf')
    })
    this.setState({ isReady: true })
  }

  render () {
    if (!this.state.isReady) {
      return <ActivityIndicator />
    }
    return (
      <View>
        <AppHeader />
      </View>
    )
  }
}

it helps some times I'm creating a project with React-Native, and currently when I try to compile my code I get an error saying undefined is not an object (evaluating '_expo_.Asset.loadAsync') , This worked for me in similar code:
Install :
code :
import * as Font from 'expo-font'; 
...
...

async componentDidMount() {
    await Font.loadAsync({
        'josefin-sans-regular': require('./assets/fonts/JosefinSans-Regular.ttf')
    });
    this.setState({ fontLoaded: true });
}

hope this fix your issue You'll need to run expo install expo-constants. Change import of app source code to
code :
import Constants from 'expo-constants';

should help you out I am getting an error at Constants in const{manifest}=Expo.Constants and showing me an error as undefined is not an object. I am not able to get it. Can anyone help me in removing that error. , The following works for me: Instead of
code :
import Expo from 'expo';
const { version } = Expo.Constants.manifest;
import Constants from 'expo-constants';
const { version } = Constants.manifest;
