How to obfuscate Flutter apps?

Question

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

Answer 1

At the moment obfuscation is not directly exposed via the flutter CLI.

You can try to explicitly pass arguements to the gen_snapshot like this:

flutter build --extra-gen-snapshot-options=--obfuscate,--save-obfuscation-map=build/symbols.json --release

Note: that obfuscation support is not very well tested and might not work at the moment.
