项目结构：Android原生项目嵌套Flutter插件
直接运行dart文件没问题，运行android项目时报错：
Abort message: '[FATAL:flutter/shell/common/shell(218)] Check failed: vm. Must be able to initialize the VM.
可能是在打包apk时未将Flutter的assets成功打入Apk引起的。

1.打开adle文件
将项目的gradle版本和Flutter的gradle版本修改一致
classpath 'ls.build:gradle:3.2.1'
2.打开Flutter_module(项目依赖的库)目录下的.android/adle,如下图，加入自己项目的签名，让fluuter无论在debug/release模式下生成的Assets和主项目对应起来。
buildTypes {
profile {
initWith debug
}
release {
// TODO: Add your own signing config for the release build.
// Signing with the debug keys for now, so `flutter run --release` works.
signingConfig signingConfigs.debug
}
}
我修改是这样的
signingConfigs {
sigin {
keyAlias 'xxxxx'
keyPassword 'xxxxxxx'
storeFile file('/Users/zhaowenwen/Desktop/Cysh(new)/key/xxxxxx.jks')
storePassword 'xxxxxxxx'
}
}
compileOptions {
targetCompatibility 1.8
sourceCompatibility 1.8
}
buildTypes {
debug {
signingConfig signingConfigs.sigin
}
release {
signingConfig signingConfigs.sigin
}
}
运行 main.dart，ok
运行项目，跳转flutter。ok
说明debug模式下完全正常了。
测试release包
在AndroidStudio终端中输入
flutter build app.

打包成功，assembleRelease生成成功，不管他，直接签名apk，安装apk，发现出问题了。。。
原Flutter中的图片不显示了，用到的返回键按钮显示也异常，
这是dart文件中的代码。
Widget getActionBar(String title, Widget body) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
leading: GestureDetector(
onTap: _onBack,
behavior: HitTestBehavior.opaque,
child: Padding(
padding: ly(left: 10),
child: Icon(Icons.arrow_back_ios)),//这个返回键异常
),
backgroundColor: Color(0xff10E5EA),
title: new Text(
title,
style: TextStyle(color: Colors.white, fontSize: 20),
),
centerTitle: true,
),
body: body,
));
}
异常如图：

寻找解决方案中...
找到问题出在新版本的adle中在打包release时少copy了一些东西。
涉及改动较多，对比图片复制对应代码到新的adle中，文章末尾有我的adle全部文件内容

Boolean buildSharedLibraryValue = false
if (project.hasProperty('build-shared-library')) {
buildSharedLibraryValue = project.property('build-shared-library').toBoolean()
}

Boolean buildSharedLibrary

if (buildSharedLibrary) {
args "--build-shared-library"
}

CopySpec getAssets() {
pySpec {
from "${intermediateDir}"
include "flutter_assets/**" // the working dir and its files
if (buildMode == 'release' || buildMode == 'profile') {
if (buildSharedLibrary) {
include "app.so"
} else {
include "vm_snapshot_data"
include "vm_snapshot_instr"
include "isolate_snapshot_data"
include "isolate_snapshot_instr"
}
}
}
}
最后跟之前打包release的方式一样
先 flutter build apk ok
签名自己的android项目 ok
安装签名后的apk ok
打开看看效果
