无法打开文件，路径='assets / responseFile'（操作系统错误：无此类文件或目录，errno = 2）

Question

我正在尝试写入存储在android Studio资产中的现有txt文件。但是，它会引发错误

assets:
  - assets/responseFile.txt

这是我的代码：

String content =  response.body.toString();
String path = "assets/responseFile.txt";
var file = new File(path);
file.writeAsString(content);

我也尝试过这种方式。但是没有运气

writingFile(String content) async {
  Directory appDocDir = await getApplicationDocumentsDirectory();
  String filePath = '${appDocDir.path}/assets/responseFile.txt';
  new File(filePath).writeAsString(content);}

Answer 1

您的pubspec.yaml错误。应该是：

flutter:
  assets:
    - assets/responseFile.txt #This in case the file is stored in the "assets" folder on the root of your Flutter project.

此外，您必须确保尊重标识。
