背景：
1、新版本1.12+与老版本引入方式发生了变化，特此记录
2、FlutterView已经废弃，替换为FlutterFragment，但它不支持生命周期管理，需要借助Activity

开始打包
1、首先连接真机，run一下，保证正常启动Flutter应用
2、flutter clean（在flutter根目录输入）
3、flutter build aar
注意：如果flutter工程中使用第三方库那么需要用到fat-aar 插件工具

接入方式一（依赖本地仓库）
Open <host>/app/build.gradle
-
Ensure you have the repositories configured, otherwise add them:
repositories { maven { url '/Users/niudong/Desktop/Project/android/flutter_library/build/host/outputs/repo' } maven { url '$storageUrl/download.flutter.io' } } Make the host app depend on the Flutter module:
dependencies {
debugImplementation 'com.example.flutter_library:flutter_debug:1.0'
profileImplementation 'com.example.flutter_library:flutter_profile:1.0'
releaseImplementation 'com.example.flutter_library:flutter_release:1.0'
}
- Add the
profilebuild type:
android {
buildTypes {
profile {
initWith debug
}
}
}
详细介绍：

接入方式二 (不依赖本地仓库) 推荐
1、找到你的flutter根目录下的build/host/outputs/repo，将flutter_release-1.0.aar复制到android项目下
/Users/niudong/Desktop/Project/android/flutter_library/build/host/outputs/repo/com/example/flutter_library/flutter_release/1.0

2、打开你的安卓工程，将aar copy到libs目录下
image.png
3、app build.grade配置 也可以上传maven
repositories {
flatDir {
dirs 'libs' // aar目录
}
}
添加如下：
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation(name: 'flutter_release-1.0', ext: 'aar')
implementation 'io.flutter:flutter_embedding_release:1.0.0-626244a72c5d53cc6d00c840987f9059faed511a'
implementation 'io.flutter:armeabi_v7a_release:1.0.0-626244a72c5d53cc6d00c840987f9059faed511a'
implementation 'io.flutter:arm64_v8a_release:1.0.0-626244a72c5d53cc6d00c840987f9059faed511a'
implementation 'io.flutter:x86_64_release:1.0.0-626244a72c5d53cc6d00c840987f9059faed511a'
}
注意：1.0.0-626244a72c5d53cc6d00c840987f9059faed511a 来自哪里呢？
姿势：找到flutter根目录下的build/host/outputs/repo, 将flutter_release-1.0.pom，里面有如下flutter基础库的地址
<groupId>com.example.flutter_library</groupId>
<artifactId>flutter_release</artifactId>
<version>1.0</version>
<packaging>aar</packaging>
<dependencies>
<dependency>
<groupId>io.flutter.plugins.sharedpreferences</groupId>
<artifactId>shared_preferences_release</artifactId>
<version>1.0</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>io.flutter</groupId>
<artifactId>flutter_embedding_release</artifactId>
<version>1.0.0-626244a72c5d53cc6d00c840987f9059faed511a</version>
<scope>compile</scope>
</dependency>
4、外层build.grade配置
buildscript {
repositories {
google()
jcenter()
maven {
url "http://download.flutter.io"
}
}
dependencies {
classpath 'com.android.tools.build:gradle:4.0.0'
}
}
5、组件化工程通常是在某个module/lib下依赖，比如module_flutter
在module_flutter build.gradle下配置
repositories {
flatDir {
dirs 'libs' // aar目录
}
}
在主App 下配置
repositories {
// 详细路径
flatDir {
dirs 'libs', '../module_flutter/libs'
}
}
6、在你的MainActivity 加入如下代码
import androidx.appcompat.app.AppCompatActivity;
import io.flutter.embedding.android.FlutterActivity;
import io.flutter.view.FlutterMain;
/**
* 原生安卓跳转Flutter
*/
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
FlutterMain.startInitialization(this);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startActivity(FlutterActivity.createDefaultIntent(this));
}
}
7、在你的清单文件中加入FlutterActivity，注意导包io.flutter.embedding.android
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.androiddemo">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:name=".FlutterApplication"
android:theme="@style/AppTheme">
<activity android:name="io.flutter.embedding.android.FlutterActivity"/>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
8、run你的Android程序，将看到：

9、与Flutter通信
public class BaseFlutterActivity extends FlutterActivity {
//跳转该页面的时候可以传要跳转的页面,参数名固定为route
private static final String ROUTE_PAGE = "route";
private static final String CHANNEL = "channel_test";
public void onCreate(@Nullable Bundle savedInstanceState) {
//初始化Flutter
super.onCreate(savedInstanceState);
new MethodChannel(getFlutterEngine().getDartExecutor().getBinaryMessenger(), CHANNEL).setMethodCallHandler(
(call, result) -> {
if (call.method.equals("getRes")) {
Toast.makeText(BaseFlutterActivity.this, "来自 flutter 的 toast ", Toast.LENGTH_LONG).show();
result.success("我是Android App");
} else if (TextUtils.equals("exit", call.method)) {
finish();
} else {
result.notImplemented();
}
});
}
}
