FlowKit — Screen Flow & Gamepad Navigation for UI Toolkit

Unity's UI Toolkit is built for laying out UI, but it stops there — it has no screen manager, no transitions between screens, and no focus handling for keyboard or gamepad. FlowKit adds all of that on top: a screen navigation stack, transition assets, and focus that works with mouse, keyboard and gamepad.

List your screens in one asset, wire the buttons in the Inspector, press Play.

Screen flow

• One FlowDefinition lists every screen (a name and a UXML).
• A real navigation stack: Push, Pop, Back, Show, Replace, ClearTo.
• Buttons wired with an Inspector component — no flow code.

Keyboard and gamepad focus

• Stick and d-pad move focus, A selects, B or Esc goes back.
• A visible focus ring follows the selection; lists scroll to keep it on screen.
• Focus stays inside an open modal and never gets trapped.
• Works on mouse, keyboard and gamepad, on both input backends.

Transitions

• Eight presets (fade, slide, scale, cascade), or make your own — duration, easing, child stagger. Interruptible: switching mid-animation never desyncs.

Modals and dialogs

• await Flow.Confirm / Alert / Prompt, or your own UXML dialogs.
• Modal overlays with a focus trap, a priority popup queue, and non-blocking toasts.

Async screens

• Load data before a screen appears: the previous screen stays under a dimmed loader, then the new one reveals already filled. Esc cancels cleanly.

Also included

• Tab groups that keep their state (Q/E or gamepad shoulders).
• UnityEvent hooks for screen lifecycle.
• An F8 debug overlay: screen stack, modals, queue, focus, recent events.
• A visual Flow Map editor that wires buttons by dragging.

Works with any UXML — your own layouts, sprite-based art, or a component kit. Three self-contained demo scenes are included: plain UXML, a USS-styled skin, and a 9-sliced sprite skin.

Requires Unity 6 or newer. No dependencies. Built-in, URP and HDRP.

Pairs well with MinimalUIKit (sold separately) if you want ready-made themeable components.
