因Flutter升级，FlutterGo暂停维护，这里导入的项目只能切回到旧版本，这里为了适应新版本的Flutter和Dart，我们新建项目，升级flutter-go，并记录学习。
1、按照之前的说明，新建一个flutter_go的Flutter项目，修改build.gradle文件
buildscript {
ext.kotlin_version = '1.3.50'
repositories {
// google()
// jcenter()
maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/google' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }
maven { url 'https://storage.googleapis.com/download.flutter.io' }
maven { url 'https://maven.fabric.io/public' }
}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
allprojects {
repositories {
// google()
// jcenter()
maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/google' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }
maven { url 'https://storage.googleapis.com/download.flutter.io' }
maven { url 'https://maven.fabric.io/public' }
}
}
rootProject.buildDir = '../build'
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
project.evaluationDependsOn(':app')
}
task clean(type: Delete) {
delete rootProject.buildDir
}
2、首先修改pubspec.yaml文件,将依赖库dependencies升级到最新版本,将静态文件和widgets添加到配置中。

3、将下载下来的FlutterGo项目中main.dart代码复制到我们新建的main.dart中，点击Android Studio右上角的Get Dependencies，下载依赖包，下载完成之后，代码中有很多报错，我们一步一步修改，先将不需要的代码注释掉，只保留首页需要用到的代码。
4、复制FlutterGo项目中lib/api，lib/blocs，lib/components，lib/event，lib/model，lib/page_demo_package，lib/resources，lib/routers，lib/standard_pages，lib/utils，lib/widgets文件夹下所有代码到新建的项目中，将FlutterGo项目中assets文件夹复制到新建项目的根目录下。
5、修改main.dart,application.dart,routers.dart文件中的Router为FluroRouter，因fluro最新版本升级，Router命名有修改。
6、修改net_utils.dart文件，引入import 'package:dio_cookie_manager/dio_cookie_manager.dart';
7、修改search_input.dart文件，将isInitialRoute: false，修改为arguments: {'isInitialRoute': false}
8、注释掉报错的导入，暂时只保留views里面首页相关页面。
9、修改flutter_go\android\app\src\main\AndroidManifest.xml文件，添加
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.MODE_WORLD_READABLE" />
<uses-permission android:name="android.permission.MODE_WORLD_WRITEABLE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
10、修改flutter_go\android\app\build.gradle文件,将以下代码复制到defaultConfig标签里。
manifestPlaceholders = [
JPUSH_PKGNAME : "com.alibaba.fluttergo",
JPUSH_APPKEY : "62eb07d227d1f11dd7fa6239", //JPush上注册的包名对应的appkey.
JPUSH_CHANNEL : "developer-default",
]
11、在lib下新建views目录，将FlutterGo项目中login_page,first_page目录和home.dart文件复制进去，然后修改login_page.dart中的timeInSecForIos为timeInSecForIosWeb。
12、修改search_page.dart文件中的suggestion.dispatch为suggestion.add
13、将FlutterGo中的welcome_page和fourth_page目录复制到我们新建的项目中。修改fourth_page.dart文件中的import 'package:flutter/material.dart'; 改为import 'package:flutter/material.dart' hide Page;
14、将FlutterGo中的lib/views下的widget_page，collection_page,issuse_message_page,standard_demo_page目录复制到我们新建的项目中。修改issuse_message_page.dart文件，将timeInSecForIos改为timeInSecForIosWeb，将ZefyrToolbarTheme改为ToolbarTheme
15、将FlutterGo下的lib/widgets目录复制到我们新建的项目中。
注意事项：
1、将classpath 'io.fabric.tools:gradle:1.26.1'改为classpath 'io.fabric.tools:gradle:1.25.4'
2、A problem occurred configuring project ':city_pickers'.
3、将Router改为FluroRouter
4、欢迎页不展示，以及图标不展示，打开注释掉的welcome page
5、如果jar包不能下载，将maven { url 'storage.googleapis.com/download.fl…' }放到maven { url 'maven.fabric.io/public' }上面
