如何删除Button边框和视图边界之间的空间尝试设置padding为0dp但没有结果。
这些是具有默认样式的材质按钮。

时间线片段

class TimelineFragment : Fragment() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        
        val axis = MaterialSharedAxis.Z

        val forward = MaterialSharedAxis(axis, true)
        val backward = MaterialSharedAxis(axis, false)

        enterTransition = forward
        exitTransition = forward
        reenterTransition = backward
        returnTransition = backward
    }

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ) = ComposeView(requireActivity()).apply { 
        setContent { 
            Text(text = "Testing")
        }
    }
}

当从此片段单击后退按钮时，应用程序崩溃并打印此堆栈跟踪
