Nipaplay Theme UI

Nipaplay Theme UI

Use this skill for any task that creates, changes, or reviews UI in the Nipaplay theme.

Required Workflow

1. Inspect the UI reference page first:
   • lib/themes/nipaplay/pages/settings/nipaplay_ui_preview_window.dart
   • In the app, it is opened from Developer Options as Nipaplay 设计 UI 预览.
2. Identify the UI pattern needed from the preview:
   • Main tabs
   • Fluent-style switches
   • Project dropdowns
   • Hover-scale text/icon buttons
   • Settings rows
   • Settings cards and divided containers
   • Nipaplay windows/dialogs
3. Find and reuse the matching widget under:
   • lib/themes/nipaplay/widgets/
4. Only create a new widget when no suitable widget exists.
5. If a missing pattern is reusable, add it under lib/themes/nipaplay/widgets/ first, then use it from the page.

Reuse Rules

• Do not hand-write a duplicate MouseRegion + GestureDetector + AnimatedScale button in a page. Use HoverScaleTextButton.
• Do not use Flutter default TabBar styling directly for Nipaplay UI. Use NipaplayMainTabBar and HoverZoomTab.
• Do not inline settings-row/card visuals in pages when SettingsItem, SettingsCard, NipaplayDemoSection, or existing Nipaplay widgets cover the pattern.
• Do not keep one-off UI state in a page solely for hover color/scale if an existing widget already handles it.
• All Nipaplay-theme-specific reusable controls must live in lib/themes/nipaplay/widgets/.

Common Widgets

• Tabs: NipaplayMainTabBar, HoverZoomTab
• Hover text/icon button: HoverScaleTextButton
• Dropdown: BlurDropdown
• Switch: FluentSettingsSwitch
• Settings rows: SettingsItem
• Settings cards/containers: SettingsCard, NipaplayDemoSection
• Windows/dialog shells: NipaplayWindow, NipaplayWindowScaffold, BlurDialog

Review Checklist

• Did the implementation check the developer-options UI preview first?
• Does the page import reusable widgets from lib/themes/nipaplay/widgets/?
• Are there duplicated hover buttons, tabs, cards, switches, or dropdowns?
• If a new widget was added, is it under lib/themes/nipaplay/widgets/?
• Does the UI preview need to be updated to show the new reusable component?
