我在支架上的容器上放置了边框半径。我现在想要的是让TabBar指示器与容器一起向下弯曲,而不是直线弯曲,从而导致指示器漂浮在背景上方。该图像将显示我的意思。
我尝试使用TabBar的indicator属性,但没有成功。

这是您可以尝试的方法,请记住,一切都是扑朔迷离的小部件,因此,首先在脚手架内创建 Stack ,将 TabBar()和< strong> Container(),使用“位置”或任何其他位置,使其重叠到所需程度,然后您应将Custom Indicator(在您的情况下,这是一个带有圆边的容器)添加到 TabBar ()。
当然,有几种可能的方法可以做到这一点,但这是我能想到的,您也会看到相同的指示器动画。 想知道它是否有效。
