## What it is
reFlutter is a Python CLI framework for reverse engineering Flutter mobile apps by repacking APK/IPA files with a specially patched, precompiled Flutter engine. The patched library enables Burp Suite traffic interception, bypasses many certificate-pinning implementations, and exposes Dart classes, functions, and code offsets for dynamic analysis without root access or certificate installation.

## Use cases
- intercept https traffic from a flutter app with burp suite
- bypass ssl certificate pinning in a flutter mobile app
- reverse engineer an apk built with flutter
- perform dynamic analysis of a dart snapshot in a mobile app
- security test a flutter app during a bug bounty
- patch a flutter ipa for traffic monitoring on ios

## When to choose
- you are pentesting or bug-bounty hunting a Flutter-based Android or iOS app
- you need traffic interception or pinning bypass without root or installing CA certificates on the device
- you want to enumerate Dart classes, functions, and code offsets from a compiled Flutter snapshot

## When to avoid
- the target app is a native Android/iOS app not built with Flutter
- you need a general-purpose disassembler or static reverse engineering suite rather than Flutter-specific dynamic analysis
- you cannot repack and re-sign the target APK/IPA, for example due to unworkable integrity protections
