1.创建flutter module
在Android Studio Terminal中输入 如下
cd ..
flutter create -t module <module_name>
在原应用父级目录下创建flutter module,如果想将flutter module当做原应用的子module,则省去cd ..这一步,<module_name>为你的flutter module名
2.为你的app添加flutter module依赖
(1)在原应用的setting.gradle下添加如下代码
setBinding(new Binding([gradle:this]))
evaluate(new File(
settingsDir.parentFile, //若做为原应用的子mudule,则为settingsDir
'<module_name>/.android/include_flutter.groovy'
))
(2)在原应用的build.gradle下的dependencies 添加flutter依赖
compile project(':flutter')
我的gradle版本较低,用的是compile,高版本用implementation,与原应用保持一致
3.执行sync 没报错就成功了,但是编辑flutter要再打开个窗口,open你的fullter module
4.原生Activity跳转至flutter
在activity中以view的形式加载flutter,参考如下
public class FlutterActivity extends BaseActivity {
private FlutterView flutterView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tr_activity_empty);
flutterView= Flutter.createView(this,getLifecycle(),"route1");
FrameLayout.LayoutParams layout=new FrameLayout.LayoutParams(
FrameLayout.LayoutParams.MATCH_PARENT,FrameLayout.LayoutParams.WRAP_CONTENT);
addContentView(flutterView,layout);
}
}
在flutter的main.dart中处理路由
import 'dart:ui';
import 'package:flutter/material.dart';
void main() => runApp(_widgetForRoute(window.defaultRouteName));
Widget _widgetForRoute(String route) {
switch (route) {
case 'route1':
return SomeWidget(...);
case 'route2':
return SomeOtherWidget(...);
default:
return Center(
child: Text('Unknown route: $route', textDirection: TextDirection.ltr),
);
}
}
以下为我遇到的问题
-
Gradle DSL method not found: 'google()'
原因:因为我的gradle版本太低,而flutter的gradle版本较高
解决办法:打开flutter安装目录下 packages/flutter_tools/gradle/flutter.gradle文件,替换 google()为maven {
url 'https://maven.google.com/'
}
2.Could not download asm-util.jar
打开settring../ Build../Gradle 取消 offline work选项
3.buildToolsVersion等版本问题
将flutter module下 .android /Flutter/build.gradle下相关版本设置与原应用
保持一致
