Reverse engineer and intercept traffic from Flutter/Dart mobile apps using blutter, reFlutter, and Frida. Use when an APK or IPA contains libflutter.so, libapp.so, App.framework, or flutter_assets, when jadx shows only a thin Dart wrapper, when Burp or mitmproxy sees no traffic from an app that is clearly online, or when the target is described as built with Flutter or Dart.

# Reversing Flutter Apps

Flutter breaks both halves of the standard mobile workflow at once. Dart is
AOT-compiled to a native snapshot, so there is no dex for jadx to decompile —
and the Flutter engine ships its own BoringSSL with its own trust store, so it
ignores the system proxy *and* the user CA store, and your interception proxy
sees nothing. Neither failure is obvious from the symptoms, which is why
people burn hours on this before recognizing what they are looking at.

## When to Use

- `jadx` on the APK shows a near-empty `MainActivity` and little else
- The APK contains `lib/arm64-v8a/libflutter.so` and `libapp.so`, or
  `assets/flutter_assets/`
