Flutter：将 Proguard 与 Gradle 7.0.4 结合使用
我刚刚更新到 Gradle 7.0.4，在构建时我现在收到错误。
A problem occurred evaluating project ':app'.
No signature of method: build_9gq7rvxos4tcg7upa17qqy1oj.android() is applicable for argument types: (build_9gq7rvxos4tcg7upa17qqy1oj$_run_closure3) values: [build_9gq7rvxos4tcg7upa17qqy1oj$_run_closure3@558fca1c]
由于错误指向我的 app/build.gradle 中的 android{} 标记，我尝试注释掉 android{} 标记的不同部分。 摆脱错误，所以我的问题是我必须在代码中更改什么才能实现这一点。
android {
/* More code */
buildTypes {
release {
signingConfig signingConfigs.release
// These lines seem to have caused the error:
// minifyEnabled true
// useProguard true
// proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
我设法通过注释掉 Proguard:但是，我仍然想使用 proguard 来
I just updated to Gradle 7.0.4 and upon build I now get the error.
A problem occurred evaluating project ':app'.
No signature of method: build_9gq7rvxos4tcg7upa17qqy1oj.android() is applicable for argument types: (build_9gq7rvxos4tcg7upa17qqy1oj$_run_closure3) values: [build_9gq7rvxos4tcg7upa17qqy1oj$_run_closure3@558fca1c]
As the error pointed to the android{} tag in my app/build.gradle I tried commenting out different sections of the android{} tag. I managed to get rid of the error by commenting out Proguard:
android {
/* More code */
buildTypes {
release {
signingConfig signingConfigs.release
// These lines seem to have caused the error:
// minifyEnabled true
// useProguard true
// proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
However, I would still like to use proguard so my question is what I have to change in my code to make this happen.

从 Gradle 7.0.0 开始，“useProguard”行已被删除。如果没有这个，Flutter 应该会进行混淆，但如果需要，您可以添加
shrinkResources true。Android R8 是使用 Proguard 的替代方案，具有自己的设置；只要您配置了此功能，您可能就需要考虑切换。
The 'useProguard' line has ben removed, as of Gradle 7.0.0. Flutter should obfuscate without this, but you can add
shrinkResources true, if you want.Android R8 is an alternative to using Proguard, with its own settings; as long as you're configuring this, you might want to look into switching.
