flutter 一键打出不同包名、应用名、版本名、签名、应用图标、版本号的安装包

在Flutter中，可以通过修改项目根目录下的pubspec.yaml文件和android和ios目录下的配置文件来实现不同的包名、应用名、版本名、签名和应用图标、版本号。

以下是一个简化的例子，展示如何在pubspec.yaml中设置不同的包名和应用名，以及如何在android和ios目录中分别设置应用图标和版本信息。

pubspec.yaml 示例：

name: MyApp
description: A new Flutter application.
 
# The following defines the version and build number for the application.
# The version number comes from the pubspec.yaml file.
version: 1.0.0+1
 
# The following sets the application identifier (package name).
# This is typically used as an internal name, and must be unique on the store.
# The "com.example" part is a reverse domain name style to help prevent naming conflicts.
# The "my_app" part is the actual name of the app.
# You can change these to your own values.
# 包名
package_name: com.example.myapp
 
# The following defines the application's name.
# This is the name that users see.
# You can change these to your own values.
# 应用名
app_name: My App
 
# The following section is for setting up icons and launcher images.
# You can replace these with your own icons and images.
# android和ios目录中会有更详细的设置
 
# 版本号和版本名
# 这些信息会显示在用户设备上的应用信息中

android/app/build.gradle 示例：

android {
    compileSdkVersion 30
 
    defaultConfig {
        // 应用ID
        applicationId "com.example.myapp"
        minSdkVersion 23
        targetSdkVersion 30
        versionCode 1
        versionName "1.0.0"
    }
 
    // ...
}
 
// 签名配置
signingConfigs {
    release {
        storeFile file('my-release-key.keystore')
        storePassword 'password'
        keyAlias 'MyReleaseKey'
        keyPassword 'password'
    }
}
 
// 应用图标和启动图标配置
android {
    // ...
 
    defaultConfig {
        // ...
 
        // 应用图标
        applicationIcon "app/src/main/res/mipmap-xxhdpi/ic_launcher.png"
    }
 
    // ...
}

ios/Runner/Info.plist 示例：

<dict>
    <!-- ... -->
 
    <!-- 应用名 -->
    <key>CFBundleName</key>
    <string>My App</string>
 
    <!-- 应用显示名 -->
    <key>CFBundleDisplayName</key>
    <string>My App</string>
 
    <!-- 应用图标 -->
    <key>CFBundleIconFiles</key>
    <array>
        <string>Icon-App-76x76@2x.png</string>
        <string>Icon-App-120x120@2x.png</string>
        <string>Icon-App-152x152@2x.png</string>
        <!-- ... -->
    </array>
 
    <!-- 版本信息 -->
    <key>CFBundleShortVersionString</key>
    <string>1.0.0</string>
    <key>CFBundleVersion</key>
    <string>1</string>
 
    <!-- ... -->
