---

A complete UI workflow framework for Godot 4.x — push/pop pages by class, animate transitions, bind data, and ship gamepad-ready prompts without reinventing the stack every project.

Features

• Stack-based Navigation — Push/pop/replace pages with lifecycle callbacks
• Class-based Routing — Reference pages by class_name, no strings needed
• Transition System — Built-in presets (fade, slide, scale) + custom transitions; preview enter/exit directly in the editor
• Data Binding — Reactive Resource + Signal pattern for data-driven UI
• Event Bus — Decoupled cross-system communication via native Signals
• Components — Toast, Confirm Dialog, Alert Dialog, Inventory Grid, workflow glue, input prompts
• Gamepad UX — Focus navigation, ActionBar prompts, AxisBinder for stick-driven sliders
• Dual Language — GDScript core with C# wrapper bridge
• Editor Tools (Pro) — Pro Hub with Theme Editor, Page Viewer, Navigation Flow Graph, and UIFlowDebugger

Quick Start

1. Enable the Plugin

1. Copy addons/ui_flow/ to your project
2. Project Settings → Plugins → Enable "UI Flow"

2. Create a Page

# home_page.gd
class_name HomePage extends UIFlowPage

func _on_opened(data: Variant = null) -> void:
    super._on_opened(data)
    print("Home page opened!")

func _on_back() -> void:
    UIFlow.push(SettingsPage)

3. Place the Scene

Place HomePage.tscn in res://UIScene/ (configurable in Project Settings).

4. Navigate

# In your main scene
func _ready() -> void:
    UIFlow.push(HomePage)

Pro Editor Tools

When addons/ui_flow_pro/ is enabled, the UIFlow Pro Hub dock provides:

• Page Viewer — thumbnails of every UIFlowPage scene; right-click to open scene/script or re-render
• Navigation Flow Graph — auto-scan static push / replace / push_instance calls and visualize page connections
• Theme Editor — visual color palette editor with presets, live preview, and undo/redo
• UIFlowDebugger — runtime navigation stack, page pool, event bus, and binding/subscription leak diagnostics
