dart - 使用 Flutter 在运行时更新 Assets 文件内容

Question

我刚接触 Flutter，我可以使用这种方法从 Assets 文件夹中将 XML 文件的内容作为字符串加载

Future<String> loadAsset() async {
    return await rootBundle.loadString('assets/file.xml');
}

和yaml文件

flutter:
   assets:
      - assets/

而且效果很好。

我的问题是:我可以在 Flutter 应用程序的 Runtime 更新属性值或将一些节点添加到我的 XML 文件并将其保存在 Assets 文件夹中的同一位置吗？

In sentence: I want to install the application on the user's device with original file of XML and user can modify it at any time as long as the application installed.

Answer 1

没有。但是你可以使用 path_provider将修改后的文件保存在app目录中。

https://flutter.dev/docs/development/ui/assets-and-images

An asset is a file that is bundled and deployed with your app, and is accessible at runtime.

...

During a build, Flutter places assets into a special archive called the asset bundle, which apps can read from at runtime.
