## Overview

Mightier Amp is a Flutter app for controlling NUX Mighty amplifiers. The principal workflow is a user controlling an amp through the app’s BLE connection; the README also documents local preset sharing, MIDI/HID control, jam-track editing and playback, and tempo training. The supplied tree contains native plugin and platform-host code but no Dart application sources, so feature-level app components have no supported source path and their internal wiring cannot be verified. The graph shows documented capabilities and the native integrations that are evidenced, without inferring app-side call chains.
