dragStartPosition property

Duration? dragStartPosition

拖拽起始位置，由底部栏拖拽回调管理。 Drag start position, managed by bottom bar drag callbacks.

每个 SlotBuildContext 实例独立，避免多播放器实例间状态串扰。 Each SlotBuildContext instance is independent, preventing state interference between multiple player instances.

Implementation

Duration? dragStartPosition;
