Flutter运行慢以及兼容AndroidX

一、修改android目录下的build.gradle文件

// Generated file. Do not edit.

buildscript {
    repositories {
//        google()
//        jcenter()
        // 使用阿里云
        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'
    }

    subprojects {
        project.configurations.all { // 解决AndroidX的冲突
            resolutionStrategy.eachDependency { details ->
                if (details.requested.group == 'com.android.support'
                        && !details.requested.name.contains('multidex')) {
                    details.useVersion "27.1.1"
                }
                if (details.requested.group == 'androidx.core'
                        && !details.requested.name.contains('androidx')) {
                    details.useVersion "1.0.1"
                }
            }
        }
    }
}

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
}

二、修改D:\saftware\flutter\packages\flutter_tools\gradle下面的flutter.gradle文件

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' }
    }
