[Question]为什么音频组件，第二次播放报错

[Qye-Leisure]

Question

经过测试稳定版（0.28）没有这个问题，有问题的是0.7版本，第一次点击播放等待播放完毕，第二次点击就会报错。

Code sample

import flet as ft
import flet_audio as fta


def main(page: ft.Page):


    async def play():
        await audio.play()
    async def play2():
        audio.src="C:/Users/31264/Documents/录音/录音.MP3"
        audio.update()
        print("Sdfa")
        await audio.resume()
        await audio.play()

    async def pause():
        await audio.pause()

    async def resume():
        await audio.resume()

    async def release():
        await audio.release()

    def set_volume(value: float):
        audio.volume += value

    def set_balance(value: float):
        audio.balance += value

    async def seek_2s():
        await audio.seek(ft.Duration(seconds=2))

    async def get_duration():
        duration = await audio.get_duration()
        print("Duration:", duration)

    async def on_get_current_position():
        position = await audio.get_current_position()
        print("Current position:", position)

    audio = fta.Audio(
          src="C:/Users/31264/Documents/录音/录音.MP3", 
        autoplay=False,
        volume=1,
        balance=0,
        on_loaded=lambda _: print("已加载完成"),
        on_duration_change=lambda e: print("Duration changed:", e.duration),
        on_position_change=lambda e: print("Position changed:", e.position),
        # on_loaded=lambda e: print("Position changed:"),
        on_state_change=lambda e: print("State changed:", e.state),
        on_seek_complete=lambda _: print("Seek complete"),
    )

    page.add(
        ft.Button("播放", on_click=play),
         ft.Button("再次播放", on_click=play2),
        ft.Button("暂停", on_click=pause),
        ft.Button("恢复播放", on_click=resume),
        ft.Button("释放", on_click=release),
        ft.Button("快进 2s", on_click=seek_2s),
        ft.Row(
            controls=[
                ft.Button("音量降低 ", on_click=lambda _: set_volume(-0.1)),
                ft.Button("音量增强 up", on_click=lambda _: set_volume(0.1)),
            ]
        ),
        ft.Row(
            controls=[
                ft.Button("Balance left", on_click=lambda _: set_balance(-0.1)),
                ft.Button("Balance right", on_click=lambda _: set_balance(0.1)),
            ]
        ),
        ft.Button("获取持续时间", on_click=get_duration),
        ft.Button("获取当前位置", on_click=on_get_current_position),
    )


ft.run(main)
