一些项目缺少 AndroidManifest 文件, 比如说 flutter_widget_of_the_week

[ViShadowFiend]

AndroidManifest.xml could not be found.
Please check D:\coding\flutter_projects\[OpenFlutter]Flutter-Notebook.git\mecury_project\example\flutter_widget_of_the_week\android\app\src\main\AndroidManifest.xml for errors.
No application found for TargetPlatform.android_x64.
Is your project missing an android\app\src\main\AndroidManifest.xml?
Consider running "flutter create ." to create one.

这个是 Flutter 运行时产物，可以先在项目根目录用 flutter clean 清除，再用 flutter create . 或者直接运行 flutter run 跑一次就可以了

[ViShadowFiend]

你好, 我试了 flutter clean 再 flutter run, 但是不行. AndroidManifest.xml 是 android 项目必须的文件, 它应该不是 flutter 运行时产物

[Vadaski]

我刚试了一下，提示说的比较清楚了：在项目目录下运行 flutter create .

[ViShadowFiend]

非常感谢， 原来之前我忽略了 create 后面的 .

不过现在虽然自动创建了 AndroidManifest 文件， 不过却运行不起来， 报错如下：

使用 --stacktrace 查看错误如下

兼容的类型: MainActivity无法转换为FlutterEngine
    GeneratedPluginRegistrant.registerWith(this);

我跟正常运行的项目中的 MainActivity 比对了一下， 发现代码是一模一样的， 这是哪里不对呢？烦请作者帮忙看下

MainActivity改成这样既可：

package com.litavadaski.provider_example;

import android.os.Bundle;
import io.flutter.embedding.android.FlutterActivity;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.plugins.GeneratedPluginRegistrant;

public class MainActivity extends FlutterActivity {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
//    GeneratedPluginRegistrant.registerWith(this);
  }

  @Override
  public void configureFlutterEngine(FlutterEngine flutterEngine) {
    GeneratedPluginRegistrant.registerWith(flutterEngine);
  }
}

非常感谢!
