flutter - 无法使用 Flutter amplify 将文件上传到 s3

Question

每当我尝试将图像上传到我在颤振中创建的 s3 存储桶时，什么都没有发生。

    final pickedFile = await picker.getImage(source: ImageSource.gallery);
    try{
    setState(() {
      if (pickedFile != null) {
        _image = File(pickedFile.path);
        
        
      } else {
        print('No image selected.');
      }
    });
    print("here");
    final key = new DateTime.now().toString();
    print(key);
    Map<String, String> metadata = <String, String>{};
metadata['name'] = 'filename';
metadata['desc'] = 'A test file';
S3UploadFileOptions options = S3UploadFileOptions(accessLevel: StorageAccessLevel.private, metadata: metadata);
try {
  UploadFileResult result = await Amplify.Storage.uploadFile(
    key: key,
    local: _image,
    options: options
  );
  print("Uploaded");
} on StorageException catch (e) {
  print(e.message);
}
}catch (e){
      Alert(
          context: context,
          type: AlertType.error,
          desc: "Error Uploading File: " + e.toString());
    }

  }

我找到了关于主题https://github.com/aws-amplify/amplify-android/discussions/550的讨论，但是我没有 amplifyconfiguration.json 文件，我有 .dart 形式的文件。我的所有信息也都存在。我不确定为什么我无法上传到 s3。先感谢您！

final pickedFile =
    await ImagePicker().getImage(source: ImageSource.gallery);

if (pickedFile != null) {
  var imagePath = pickedFile.path;
  var nameWithExtension = imagePath.split('/')[6];
  var imageName = nameWithExtension.split('.')[0];
}

use imagePath in local
