First import dependencies:

# 图片选择器
image_picker: ^0.6.7+17

how to use:

Directly on the code:

//实例化选择图片
final ImagePicker picker = new ImagePicker();
//用户本地图片
File _userImage;//存放获取到的本地路径
//异步吊起相机拍摄新照片方法
Future _getCameraImage() async {
  final cameraImages = await picker.getImage(source: ImageSource.camera);
  if (mounted) {
    setState(() {
      //拍摄照片不为空
      if (cameraImages != null) {
        _userImage = File(cameraImages.path);
        print('你选择的路径是：${_userImage.toString()}');
        //图片为空
      } else {
        print('没有照片可以选择');
      }
    });
  }
}
Future _getImage() async {
  //选择相册
  final pickerImages = await picker.getImage(source: ImageSource.gallery);
  if(mounted){
    setState(() {
      if(pickerImages != null){
        _userImage = File(pickerImages.path);
        print('你选择的本地路径是：${_userImage.toString()}');
      }else{
        print('没有照片可以选择');
      }
    });
  }
}

Core code:

//Call the camera to take pictures
final cameraImages = await picker.getImage(source: ImageSource.camera);
//Select the album
final pickerImages = await picker.getImage(source: ImageSource.gallery);

Then use a button or something to get a click event. The
image path needs to be connected with the File type.

It should be noted that the
pictures taken by this Demo will not be saved locally
