Flutter 无法混淆和剥离符号

Question

I'm unable to obfuscate or remove debug symbols as per this documentation https://flutter.dev/docs/deployment/obfuscate

my command:

flutter build apk --target-platform android-arm,android-arm64 --obfuscate --split-debug-info=/symbols

output:

Could not find an option named "obfuscate".


Run 'flutter -h' (or 'flutter <command> -h') for available flutter commands and options.

Answer 1

You have to check that your are at least on the on 1.16.2 version of Flutter as explained there Supported as of Flutter 1.16.2

I'm currently on the 1.17.0 version and this command is working well: flutter build apk --obfuscate --split-debug-info=<app_name>/symbols

Answer 2

upgrade your flutter using

flutter upgrade 

command and then use

flutter clean 

command to clean any previous build cache then try again.

Answer 3

One of the options which works is --[no-]shrink

flutter build apk --release --target-platform=android-arm64 --shrink

Whether to enable code shrinking on release mode. When enabling shrinking, you also benefit from obfuscation, which shortens the names of your app's classes and members, and optimization, which applies more aggressive strategies to further reduce the size of your app.
