Capture HTTP(s) traffic from Flutter Android Emulator
1-click to capture and debug all network traffic from your Flutter apps. No code changes required.
Why is Flutter traffic hard to capture?
- Flutter's Dart
HttpClientbypasses the system proxy - Charles Proxy, Fiddler, mitmproxy can't capture Flutter traffic
- Typical fix: modify code with
HttpOverrides- tedious!
Proxyman solves this with 1-click
- Installs certificate into Android system trust store
- Flutter's Dart VM respects system-level CA certificates
- No code changes required
The Solution: Proxyman's 1-Click Setup
- Open Android Emulator Setup Guide
- Certificate Menu -> Install Certificate on Android -> Emulators.
- Use Automatic Script
- Click on "Override All Emulators" button to set up HTTP Proxy and install Proxyman's certificate.
It also installs Proxyman's VPN to your Emulators, so Flutter traffic will be captured by Proxyman. - Run your Flutter app
- Launch your Flutter app from Android Studio or VS Code. All HTTP(s) traffic will be captured automatically - no code changes needed.
