Flutter踩坑集锦

1. 开发环境： Ubuntu 18.04.1 LTS
2. Could not resolve all files for configuration 'classpath'. ^[1]
   • 配置Android下的build.gradle

// Generated file. Do not edit.

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' }

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

• 配置flutter sdk中的flutter.gradle

找到fluttersdk目录,进入如下目录Flutter⁩ ▸ ⁨packages⁩ ▸ ⁨flutter_tools⁩ ▸ ⁨gradle⁩找到下 flutter.gradle文件

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

2.Flutter install get 失败
添加Flutter阿里镜像到环境变量^[2]

sudo vim /etc/profile

将以下内容^[3]添加以下到文件中

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
