# 开发环境如下 #

1.  flutter 开发环境
2.  安卓开发环境
3.  dart开发环境 目前flutter集成了dart
4.  debug.keystore 生成

# 项目配置细节 #

## flutter安卓地图配置 ##

1.  android/app 下创建libs文件，并且下载地图SDK  
    ![在这里插入图片描述][20210127135309181.png]
2.  android/app/build.gradle 配这个文件带有添加的是你项目需要修改的地方

def localProperties = new Properties()
    def localPropertiesFile = rootProject.file('local.properties')
    if (localPropertiesFile.exists()) { 
        localPropertiesFile.withReader('UTF-8') {  reader ->
            localProperties.load(reader)
        }
    }
    
    def flutterRoot = localProperties.getProperty('flutter.sdk')
    if (flutterRoot == null) { 
        throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
    }
    
    def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
    if (flutterVersionCode == null) { 
        flutterVersionCode = '1'
    }
    
    def flutterVersionName = localProperties.getProperty('flutter.versionName')
    if (flutterVersionName == null) { 
        flutterVersionName = '1.0'
    }
    
    apply plugin: 'com.android.application'
    apply plugin: 'kotlin-android'
    apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
    
    android { 
        compileSdkVersion 29//建议使用30一下版本
        sourceSets { 
            main.java.srcDirs += 'src/main/kotlin'
            //添加地图SDK引入路径
            main { 
                jniLibs.srcDirs = ['libs']
            }
        }
        signingConfigs { 
       
            //添加keystore
            release { 
                keyAlias 'androiddebugkey'
                keyPassword 'android'
                storeFile file('../debug.keystore')
                storePassword 'android'
            }
        }
        defaultConfig { 
            // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
            applicationId "com.example.flutter_app"
            minSdkVersion 16
            targetSdkVersion 29//建议使用30一下版本
            versionCode flutterVersionCode.toInteger()
            versionName flutterVersionName
        }
        
        buildTypes { 
         	//添加如下配置关闭混淆
            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
                //关闭混淆, 否则在运行release包后可能出现运行崩溃， TODO后续进行混淆配置
                minifyEnabled false //删除无用代码
                shrinkResources false //删除无用资源
                // proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }
    
    flutter { 
        source '../..'
    }
    
    dependencies { 
        implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
        //添加demo中引入高德地图SDK
        implementation fileTree(include: ['*.jar'], dir: 'libs')
    }

1.  添加安卓权限在android/app/src/main/AndroidManifest.xml  
    这里就添加的比较多了根据当前需求选择添加的权限  
    在manifest 标签下

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
    
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
    
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
    
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
    
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
    
    <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
    
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
    
    <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"></uses-permission>

1.  引入flutter插件

permission_handler: ^5.0.1+1#权限申请插件
     amap_flutter_map: ^1.0.0#高德地图插件

1.  配置这个文件android/gradle.properties 添加如下配置

android.enableR8=true

1.  配置 android/build.gradle classpath 版本目前建议3.5.0 4.1.0无法用

buildscript { 
        ext.kotlin_version = '1.3.50'
        repositories { 
            google()
            jcenter()
        }
    
        dependencies { 
            classpath 'com.android.tools.build:gradle:3.5.0'//4.1.0
            classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        }
    }

1.  配置这个文件android/gradle/wrapper/gradle-wrapper.properties  
    建议使用5.6.2 gradle-6.7-all.zip无法使用目前

distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip

1.  keystore 生成

**方案1**

dos下进入JDK的bin目录
    
    运行如下命令:
    
    keytool -genkey -alias android.keystore -keyalg RSA -validity 20000 -keystore android.keystore
    
    (-validity 20000代表有效期天数)，命令完成后，bin目录中会生成android.keystore
    
     设置密码 keytool -list -keystore "android.keystore" 输入设置的keystore密码

**方案2**
