Flutwire
Network inspector for Flutter: your app’s HTTP calls on a real phone, to open in full, edit and send again.

The video
The notification shows the latest calls. A tap opens the inspector, where a call can be read as a JSON tree. The video lasts forty seconds and was recorded on an Android emulator.
Flutwire records the HTTP traffic of your Flutter app and displays it in an interface accessible straight from the notification shade. No Wi-Fi proxy, no certificates to install.
Flutwire is a network inspector for Flutter. It solves the problem of invisible network calls on physical devices by operating entirely from your phone. Traditionally, inspecting the traffic of a running app requires complex proxies and local certificates. With Flutwire, you simply add a single instruction await Flutwire.init() in the main function to automatically intercept every outgoing call from dart:io, natively covering clients like Dio, Chopper, or the base HTTP adapter. Every completed call is written to disk as soon as it ends. This ensures that the notification survives even a brutal closure of the app. Tapping the notification gives access to the full inspector, where you can explore response times, headers, cookies, and decoded bodies, including structured formats like JSON and Protobuf. Three satellite modules allow Flutwire to hook into isolated traffic, including Firebase callable functions. Before writing to disk, it automatically masks authorisation headers and cookies. More importantly, in a release build, the entire package remains inactive, logging nothing and triggering no notifications.
