无法从 flutter web 将图像上传到 Firebase Storage

Can't upload image to Firebase Storage from flutter web

所以我试过这个来获取图像并上传它:

var file;
      html.InputElement uploadInput = html.FileUploadInputElement()
        ..accept = "image/*";
      uploadInput.click();
      uploadInput.onChange.listen((event) {
        file = uploadInput.files.first;
        final reader = html.FileReader();
        reader.readAsDataUrl(file);
        reader.onLoadEnd.listen((event) async {
          print("done");
          StorageReference storageReference = FirebaseStorage.instance
              .ref()
              .child('${widget.uid}/${DateTime.now()}');
          StorageUploadTask uploadTask = storageReference.putData(file);
          await uploadTask.onComplete;
          print('File Uploaded');
          print(storageReference.path);
          storageReference.getDownloadURL().then((fileURL) {
            setState(() {
              _uploadedFileURL = fileURL;
              
            });
          });
        });
      });

如教程所示,但是这个人使用 .put() 而不是 putData() 但它现在已被弃用,所以在使用 .put() 时我得到:

Expected a value of type 'File', but got one of type 'File$'

使用 .putData() 我得到:

Expected a value of type 'Uint8List', but got one of type 'File$'

关于如何从 Flutter Web 用户转换 File$ 或直接导入 File 或 Uint8List 的任何想法? 谢谢

试试 reader.readAsArrayBuffer(file)storageReference.putData(reader.result)
