androidstudio搭建flutter环境，遇到的问题

flutter支持的开发工具有ieda和androidstudio，当然还有其它的，我只搭建了这两个环境。

Windows环境下搭建

1.Androidstudio的相关环境和搭建，还有jdk的环境变量，Android的sdk配置，这里就不说了，请自行解决，并能编译一个helloWorld的app。

2.下载flutter的SDK https://flutter.io/sdk-archive，下载稳定版

3.配置环境变量，在系统环境变量的Path里面配置

例如：D:\flutter\flutter_windows_1.17.5-stable\flutter\bin

4.在androidstudio里面下载flutter

androidstudio --settings--Plugins

基本的环境变量已经配置好了，

新建flutter项目

上面就是配置到新建一个flutter项目的过程，

我是这样，但是没有运行起来，一直卡在gradle的编译位置，

最后修改如下：

你自己的磁盘:\flutter\packages\flutter_tools\gradle\flutter.gradle

这个文件比较多，需要仔细点，

buildscript {    repositories {    //注释以前的     //google()   // jcenter()     ///增加这段代码        maven { url'https://maven.aliyun.com/repository/google'}maven { url'https://maven.aliyun.com/repository/jcenter'}maven { url'http://maven.aliyun.com/nexus/content/groups/public'}    }    dependencies {        classpath 'com.android.tools.build:gradle:3.5.0'    }}

project.rootProject.allprojects {            repositories {                maven {                    url repository                }                ///增加这段代码maven { url'https://maven.aliyun.com/repository/google'}maven { url'https://maven.aliyun.com/repository/jcenter'}maven { url'http://maven.aliyun.com/nexus/content/groups/public'            }}

然后重新编译，起码能编译了，不是一直卡着不动

编译出现如下问题

方法一：再次修改刚才那个文件

class FlutterPlugin implements Plugin {//原下载路径 //private static final String MAVEN_REPO      = "https://storage.googleapis.com/download.flutter.io"; //修改后的下载路径    private static final String MAVEN_REPO      = "https://storage.flutter-io.cn/download.flutter.io"}

这样再次编译，结果就成功了

方法二：

在自己Android项目中build.gradle下

换成

allprojects {    repositories {        google()        jcenter()        maven { url "https://storage.googleapis.com/download.flutter.io" }    }}

也可以编译完成

我的build.gradle,可以参考

buildscript {    ext.kotlin_version = '1.3.50'    repositories {//        google()//        jcenter()        maven { url 'https://maven.aliyun.com/repository/google' }        maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }        maven { url 'https://maven.aliyun.com/repository/jcenter' }        maven { url 'https://maven.aliyun.com/repository/public' }    }    dependencies {        classpath 'com.android.tools.build:gradle:3.2.1'        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"    }}allprojects {    repositories {//        google()//        jcenter()        maven { url 'https://maven.aliyun.com/repository/google' }        maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }        maven { url 'https://maven.aliyun.com/repository/jcenter' }        maven { url 'https://maven.aliyun.com/repository/public' }        maven { url "https://storage.googleapis.com/download.flutter.io" }    }}rootProject.buildDir = '../build'subprojects {    project.buildDir = "${rootProject.buildDir}/${project.name}"}subprojects {    project.evaluationDependsOn(':app')}task clean(type: Delete) {    delete rootProject.buildDir}
