如何混淆 Flutter 应用程序? [英] How to obfuscate Flutter apps?

问题描述

Flutter 的 wiki 提到混淆是一种选择处于发布模式.
然而，flutter build 命令没有相关选项 - 请参阅:
flutter help -v build apk

Flutter's wiki mentions obfuscation is an opt-in in release mode.
And yet, the flutter build command has no relevant option - see:
flutter help -v build apk

我在这里遗漏了什么吗?
他们是否将混淆设置为默认设置?
混淆甚至与颤振相关吗?

Am I missing something here?
Did they make obfuscation the default?
Is obfuscation even relevant for flutter?

对此的任何指示将不胜感激.

Any pointers on this would be very appreciated.

推荐答案

需要混淆 - Flutter 应用程序知道其函数名称，可以使用 Dart 的 StackTrace 类显示.对混淆的支持测试不足.启用它:

Obfuscation is needed - a flutter app knows its function names, which can be shown using Dart's StackTrace class. There's under-tested support for obfuscation. To enable it:

安卓版:
添加到文件 [ProjectRoot]/android/gradle.properties :

extra-gen-snapshot-options=--obfuscate

<小时>

对于 iOS:
首先，编辑[FlutterRoot]/packages/flutter_tools/bin/xcode_backend.sh:
找到 build aot 调用，并为其添加一个标志，

---

For iOS:
First, edit [FlutterRoot]/packages/flutter_tools/bin/xcode_backend.sh:
Locate the build aot call, and add a flag to it,

${extra_gen_snapshot_options_or_none}

定义为:

local extra_gen_snapshot_options_or_none=""
if [[ -n "$EXTRA_GEN_SNAPSHOT_OPTIONS" ]]; then
  extra_gen_snapshot_options_or_none="--extra-gen-snapshot-options=$EXTRA_GEN_SNAPSHOT_OPTIONS"
fi

要应用您的更改，请在 [FlutterRoot] 中运行

To apply your changes, in [FlutterRoot], run

git commit -am "Enable obfuscation on iOS"  
flutter  

(在提交后运行flutter"重建颤振工具.)

(Running "flutter" after the commit rebuilds flutter tools.)

接下来，在您的项目中，将以下内容添加到 [ProjectRoot]/ios/Flutter/Release.xcconfig 文件:

Next, in your project, add following to [ProjectRoot]/ios/Flutter/Release.xcconfig file:

EXTRA_GEN_SNAPSHOT_OPTIONS=--obfuscate

<小时>

同样，正如@mraleph 所提到的，混淆没有经过很好的测试.
