Flutter TabBar底部去掉下划线

 

 

在界面里面，TabBar有可能不要下划线的需求，看了一下TabBar的文档，并没有隐藏属性

 

const TabBar({
  Key key,
  @required this.tabs,
  this.controller,
  this.isScrollable = false,
  this.indicatorColor,
  this.indicatorWeight = 2.0,
  this.indicatorPadding = EdgeInsets.zero,
  this.indicator,
  this.indicatorSize,
  this.labelColor,
  this.labelStyle,
  this.labelPadding,
  this.unselectedLabelColor,
  this.unselectedLabelStyle,
  this.dragStartBehavior = DragStartBehavior.start,
  this.onTap,
})

我们只需要加上下面一行代码就OK了

indicator: const BoxDecoration(),
