What is gamepads?

Gamepads is a plugin for Flutter (Google's cross-platform app toolkit) that lets your app respond to physical game controller input. If you're building a game or any app where a user might plug in a gamepad, this handles the connection, button presses, and stick movements so you don't have to. The core challenge this project solves is that every platform handles gamepad input differently. The A button might be called "a" on Windows, "KEYCODE_BUTTON_A" on Android, and "button 0" on the web. This plugin provides a "normalized" event stream that translates all those quirks into consistent names and value ranges, following an Xbox-style layout. Your code can just ask "was the A button pressed?" and get a 0.0 (released) or 1.0 (pressed) answer, regardless of platform. The same goes for analog sticks, which always report a value from -1.0 to 1.0. This is built for Flutter developers creating games or interactive apps who want to support controllers on Android, iOS, macOS, Linux, Windows, and the web. It supports multiple controllers connected at once and auto-detects new ones. If you're using the Flame game engine, there's a bridge package that ties gamepad input directly into Flame's component system. What's notable is how it handles the notoriously messy world of controller hardware. On Linux, for example, it ships with a community-maintained database of over 1,500 controllers to figure out the correct button mappings. Unknown controllers fall back to a sensible default layout. There's also an escape hatch: if you need the raw, un-translated events for a specific reason, the plugin exposes those too. Setting it up requires some platform-specific work. On Android, you'll need to add some boilerplate code to your app's main activity to route input events to the plugin. On Windows, you need the Windows SDK installed as part of your development setup, though end users of your app don't need anything extra.
