vesper_player_ui 0.5.2-rc.3

Optional Flutter UI controls and stage for Vesper Player.

vesper_player_ui

Optional Flutter UI controls and player stage built on top of vesper_player.

This package provides ready-made widgets that consume a VesperPlayerController so apps can adopt a polished player surface without re-implementing controls, gestures, fullscreen, or bottom sheets.

Status

Experimental. The widgets and APIs are not yet frozen and may change between minor releases. Pin the version explicitly when consuming.

What's Included

Exported from package:vesper_player_ui/vesper_player_ui.dart:

• VesperPlayerStage — opinionated player stage with controls overlay, gestures (double-tap play / pause, drag scrub), fullscreen toggle, and sheet entry points. Hosts can pass topBarPrimaryAction and topBarSecondaryAction for Cast, AirPlay, DLNA, or custom menu buttons that should follow the stage overlay. contentOverlay, landscapeControlBarLeading, and onNavigateBack provide content, control-row, and navigation extension points
• Stage helpers: bottom-sheet entry types, formatting helpers
• Stage models: presentation-layer DTOs consumed by VesperPlayerStage
• Stage device controls: brightness / volume gesture wiring helpers
• VesperAirPlayRouteButton — iOS AVRoutePickerView wrapper bound to the active VesperPlayerController
• VesperAirPlayRouteIconButton — stage-sized AirPlay route picker wrapper for VesperPlayerStage.topBarPrimaryAction

Installation

Use the hosted packages for normal application integration:

dependencies:
  vesper_player: 0.5.0
  vesper_player_ui: 0.5.0

Repository development first runs ./scripts/vesper flutter local-overrides. External hosts that intentionally consume a source checkout must configure the root-level federated package overrides described in the vesper_player installation guide:

dependencies:
  vesper_player:
    path: path/to/rust-player-sdk/lib/flutter/vesper_player
  vesper_player_ui:
    path: path/to/rust-player-sdk/lib/flutter/vesper_player_ui

vesper_player_ui depends on vesper_player. Apps that build their own UI can depend on vesper_player directly and skip this package.

VesperPlayerStage keeps decorative full-stage overlays non-interactive, so empty video-space gestures continue to work while controls are visible. Only the actual buttons, sheet entries, and timeline receive pointer events.

contentOverlay renders above the player view and below Stage gestures and controls. The Stage wraps it in IgnorePointer and RepaintBoundary, clips it to the player area, and removes it from Picture in Picture presentation. Hosts remain responsible for bounding the overlay's parsing, layout, cache, and paint cost.

landscapeControlBarLeading is inserted directly after the landscape play button. null adds no spacing. A host can pass fixed-size content or a direct Expanded/Flexible child. Controls that are unavailable should pass null so the remaining built-in controls retain their order.

onNavigateBack controls whether the top-left back action exists. Supply navigateBackSemanticLabel for the current mode. Set keepControlsVisible while a host input or drawer is active; changing it back to false restarts the normal auto-hide interval.

VesperAirPlayRouteButton is an iOS-only route picker. It renders an empty box on non-iOS platforms so shared control rows can keep a stable layout.

Use VesperAirPlayRouteIconButton inside a stage top-bar action slot when the AirPlay picker should hide and show with the player controls.

Set VesperPlayerStage.pictureInPicturePresentation while handing playback to system Picture in Picture. In that mode the stage renders only the video surface and disables custom overlay gestures so the platform PiP UI owns all visible playback controls.

VesperPlayerStage uses English labels by default. Apps can replace only the stage copy without rebuilding the stage controls:

VesperPlayerStage(
  controller: controller,
  snapshot: snapshot,
  isPortrait: isPortrait,
  contentOverlay: const HostContentOverlay(),
  landscapeControlBarLeading: const HostLandscapeControls(),
  onNavigateBack: exitCurrentPresentation,
  navigateBackSemanticLabel: 'Exit fullscreen',
  keepControlsVisible: activeDrawer != null || composerHasFocus,
  strings: const VesperPlayerStageStrings.zhHans(),
  onOpenSheet: onOpenSheet,
  onToggleFullscreen: onToggleFullscreen,
)
