Flutter TabBar底部去掉下划線

 

 

在界面里面，TabBar有可能不要下划線的需求，看了一下TabBar的文檔，並沒有隱藏屬性

 

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,
})

我們只需要加上下面一行代碼就OK了

indicator: const BoxDecoration(),
