使用Flutter

Question

尝试使用flutter将两张图片上传到Firebase中。该代码仅适用于一张图片，而针对两张图片进行编码！没有编译器错误！

     File _image,_imageside;

   Future getImage() async {
   var image = await ImagePicker.pickImage(source: ImageSource.gallery);
   var image2 = await ImagePicker.pickImage(source:ImageSource.gallery);

   setState(() {
      _image = image;
      _imageside = image2;
    });

 }
    final DatabaseReference database =  FirebaseDatabase.instance.reference().child("test");
    sendData(){
                final StorageReference firebaseStorageRef =
                              FirebaseStorage.instance.ref().child(name).child('front');
                              final StorageUploadTask task =         firebaseStorageRef.putFile(_image);
                              FirebaseStorage.instance.ref().child(name).child('side');
                              final StorageUploadTask task1 =
                              firebaseStorageRef.putFile(_imageside);

    };
           _image == null  ? new Text('No image selected.')  : Text('Image selected'),
                        _imageside ==null? new Text('No image selected.'):Text("Image selected"),
                         RaisedButton(
                    onPressed: getImage,

                    child: new Icon(Icons.add_a_photo),
                  ),
     RaisedButton(
                        color: Colors.blueAccent,

                        onPressed: () =>sendData(),
                        child:
                        Text("Upload Data"),
                      )

Answer 1

两个图像都使用相同的StorageReference-因此，第二个图像将覆盖第一个图像。

将FirebaseStorage.instance.ref().child(name).child('side');分配给新变量，然后用新的task1上传StorageReference。
