环境搭建

步骤

1. 下载需要的软件包

下载flutter

下载jdk（最好下载独立程序包）

下载vscode 或 Android Studio （路径和用户名非中文）

下载插件

2. 环境变量配置

flutter环境下载国内镜像配置

1	setx PUB_HOSTED_URL "https://pub.flutter-io.cn"

1	setx FLUTTER_STORAGE_BASE_URL "https://storage.flutter-io.cn"

jdk配置

新建环境变量，变量名为JAVA_HOME，值为刚刚JDK的安装目录，再新建一个CLASSPATH，值为%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar

CLASSPATH配置.png
配置系统java环境，点击Path，分别新增加%JAVA_HOME%\bin 和 %JAVA_HOME%\jre\bin

编程工具配置，以vscode为例

按下 Ctrl + ALT + P 在框内输入 flutter new project 会提示导入flutter。导入之前下载的flutter即可。注意路径不要含中文。因为刚刚设置了PUB_HOSTED_URL和FLUTTER_STORAGE_BASE_URL国内镜像源。项目初始化速度会挺快的。

3. maven和gradle下载镜像配置

镜像路径配置目录.png
settings.gradle文件配置，也可能叫settings.gradle.kts

pluginManagement {
    val flutterSdkPath = run {
        val properties = java.util.Properties()
        file("local.properties").inputStream().use { properties.load(it) }
        val flutterSdkPath = properties.getProperty("flutter.sdk")
        require(flutterSdkPath != null) { "flutter.sdk not set in local.properties" }
        flutterSdkPath
    }

    includeBuild("$flutterSdkPath/packages/flutter_tools/gradle")

    repositories {
        maven {
            url = uri("https://jitpack.io")
        }
        maven {
            url = uri("https://maven.aliyun.com/repository/google")
        }
        maven {
            url = uri("https://maven.aliyun.com/repository/public")
        }
        maven {
            url = uri("https://maven.aliyun.com/repository/center")
        }
        maven {
            url = uri("https://maven.aliyun.com/repository/gradle-plugin")
        }
        maven {
            url = uri("https://maven.aliyun.com/repository/releases")
        }
        google()
        mavenCentral()
        gradlePluginPortal()
    }
}

plugins {
    id("dev.flutter.flutter-plugin-loader") version "1.0.0"
    id("com.android.application") version "8.7.3" apply false
    id("org.jetbrains.kotlin.android") version "2.1.0" apply false
}

include(":app")

build.gradle文件配置，也可能叫build.gradle.kts

allprojects {
    repositories {
        maven {
            url = uri("https://jitpack.io")
        }
        maven {
            url = uri("https://maven.aliyun.com/repository/google")
        }
        maven {
            url = uri("https://maven.aliyun.com/repository/public")
        }
        maven {
            url = uri("https://maven.aliyun.com/repository/center")
        }
        maven {
            url = uri("https://maven.aliyun.com/repository/gradle-plugin")
        }
        maven {
            url = uri("https://maven.aliyun.com/repository/releases")
        }
        google()
        mavenCentral()
    }
}

val newBuildDir: Directory = rootProject.layout.buildDirectory.dir("../../build").get()
rootProject.layout.buildDirectory.value(newBuildDir)

subprojects {
    val newSubprojectBuildDir: Directory = newBuildDir.dir(project.name)
    project.layout.buildDirectory.value(newSubprojectBuildDir)
}
subprojects {
    project.evaluationDependsOn(":app")
}

tasks.register<Delete>("clean") {
    delete(rootProject.layout.buildDirectory)
}

gradle-wrapper.properties文件配置

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://mirrors.aliyun.com/gradle/distributions/v8.10.2/gradle-8.10.2-all.zip

4. 后续出现的问题

还是出现一直卡在

Running Gradle task ‘assembleDebug’…

需要在项目的android终端目录下执行

1
2
3

./gradlew clean   //可能出现网络卡顿，多运行几次，没问题再运行下面的build

./gradlew build
