如何使用Proguard缩小Flutter应用程序? [英] How to minify a Flutter app with Proguard?

问题描述

我已经制作了Flutter应用.该发行版APK约为14MB.我搜索了一些方法以最小化此问题，并发现了以下几点: https://flutter.io/android-release /#enabling-proguard

I already made a Flutter app. The release apk is about 14MB. I searched methods to minify this and found this ons: https://flutter.io/android-release/#enabling-proguard

但是我的问题是，我如何才能知道我在步骤1中使用的所有其他库?是否有任何命令可以了解它们，或者仅仅是我添加到pubspec.yaml的所有依赖项?

But my question is, how can I get to know all my used additional libraries for step 1? Are there any commands to know them or is it just all the dependencies that I added to the pubspec.yaml ?

如何我需要在该文件/android/app/proguard-rules.pro中实施吗?

How do I need to implement them in this file /android/app/proguard-rules.pro?

推荐答案

首先，我们将在构建文件中启用缩小和模糊处理.找到位于/android/app/文件夹中的build.gradle文件，并以粗体添加行

First, we will enable shrinking and obfuscation in the build file. Find build.gradle file which sits inside /android/app/ folder and add lines in bold

android {

    ...

    buildTypes {

        release {

            signingConfig signingConfigs.debug     

            minifyEnabled true
            useProguard true

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 

        }
    }
}

接下来，我们将创建一个配置，该配置将保留整个Flutter包装器代码.创建/android/app/proguard-rules.pro文件并插入到其中:

Next we will create a configuration which will preserve entire Flutter wrapper code. Create /android/app/proguard-rules.pro file and insert inside:

#Flutter Wrapper
-keep class io.flutter.app.** { *; }
-keep class io.flutter.plugin.**  { *; }
-keep class io.flutter.util.**  { *; }
-keep class io.flutter.view.**  { *; }
-keep class io.flutter.**  { *; }
-keep class io.flutter.plugins.**  { *; }
