DEVELOPMENT RUN

对接接口时借助 Charles 抓包析工具能提升开发效率和快速定位问题,请注意 Charles 端口是否已设置为 8888(默认值)

Charles Web Debugging Proxy

开发环境启动注意：

1.配置config/ConfigDev.dart配置

/// proxy服务器地址，只有开发环境走proxy
String getProxyUrl() {
	return '127.0.0.1:8888'; 
}

2.点击DEBUG启动按钮，选择开发环境启动

Tips:

Could not determine the dependencies of task ':app:flutterBuildDebug' when start vscode flutter debugging 错误解决办法

错误解决办法

flutter clean
然后
flutter run

生成JSON序列化文件.g.dart 
flutter packages pub run build_runner build
或者
flutter packages pub run build_runner build --delete-conflicting-outputs

Build file '../android/app/build.gradle' line: 25 错误解决办法

1：修改build.gradle,注释掉jcenter()，google()。使用阿里的镜像。原因是jcenter google库无法访问到导致的问题。

buildscript {
    repositories {
        //google()
        //jcenter()
        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:3.1.2'
    }
}

allprojects {
    repositories {
        //google()
        //jcenter()
        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' }
    }
}

2：找到fluttersdk目录 进入如下目录

Macintosh HD⁩ ▸ ⁨用户⁩ ▸ ⁨rabbit⁩ ▸ ⁨资源库⁩ ▸ ⁨Flutter⁩ ▸ ⁨packages⁩ ▸ ⁨flutter_tools⁩ ▸ ⁨gradle⁩
找到 flutter.gradle文件替换如下内容。

​buildscript {
    repositories {
        //jcenter()
        //maven {
        //    url 'https://dl.google.com/dl/android/maven2'
        //}
        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:3.1.2'
    }
} 

sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target 错误解决办法

1.访问http://maven.aliyun.com, 原因为需要将MAVEN下载的阿里云HTTPS证书手动导入JDK中认证

2.F12， 打开开发者面板，定位Security -> Overview -> View certificate

3.在打开的面板中拖动*.aliyun.com.cer证书，下载至本地目录
4.导入证书至JDK，使用如下命令

sudo keytool -import -v -trustcacerts -alias .aliyun.com -file /存放证书路径/*.aliyun.com.cer -keystore /JDK路径/Contents/Home/jre/lib/security/cacerts -keypass changeit -storepass changeit

5.重启系统
