• 提取码 zvan version: 1.22.3

2.下载 Android Studio

• 提取码 rjk2

SDK问题

[!] Android toolchain - develop for Android devices (Android SDK version 29.0.3)      X Android license status unknown.        Try re-installing or updating your Android SDK Manager.        See https://developer.android.com/studio/#downloads or visit https://flutter.dev/setup/#android-setup for detailed        instructions.

Android sdkmanager tool not found (C:\Users\petelu\AppData\Local\Android\sdk\tools\bin\sdkmanager).  Try re-installing or updating your Android SDK,  visit https://flutter.dev/setup/#android-setup for detailed instructions.

产生原因

我们自己定了了Android SDK Flutter 找不到

解决

系统环境变量中增加Android的配置

ANDROID_HOME `D:\file\android\Sdk`%ANDROID_HOME%\tools%ANDROID_HOME%\platform-tools

国内google服务访问受限制问题

已有项目修改

修改项目中android/build.gradle文件,仓库地址改为阿里云

aven { 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' }private static final String MAVEN_REPO = "https://storage.flutter-io.cn/download.flutter.io";

新建项目修改

# 修改Flutter的配置文件, 该文件在Flutter安装目录/packages/flutter_tools/gradle/flutter.gradle

留意SDK路径

arcgis 引入

rootProject.allprojects {    repositories {        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' }//        maven { url 'https://esri.bintray.com/arcgis' }        maven { url 'https://esri.jfrog.io/artifactory/arcgis' }    }}

5.Android Studio 安装

1. 设置Flutter、Dart SDK 路径

3. 安装Flutter & Dart插件

4. 设置Android SDK开启模拟器或者连接真机
   
   
   

三、创建Flutter项目

四、运行，最终效果

# 查看详细的Flutter 启动构建打包过程flutter run --verbose
