I created a custom indicator for tab bar using Decorator. I want to create a unselected indicator for not selected tabs in tab bar.

I did a container with custom decoration but current selected indicator draws behind container decoration.

new TabBar( 
labelColor: Colors.black,
unselectedLabelColor: Colors.grey,
indicator: new CustomTabIndicator(),
tabs: [
new Container(decoration: new CustomTabInactive(),child: Tab(icon: Icon(Icons.person )))])

tab bar with unselected indicator


Instead of using container in tabs, try this (wrapping the TabBar with container and providing bottom border

Container(
  //This is responsible for the background of the tabbar, does the magic
  decoration: BoxDecoration(
    //This is for background color
    color: Colors.white.withOpacity(0.0),
    //This is for bottom border that is needed
    border: Border(bottom: BorderSide(color: Colors.grey, width: 0.8))),
    child: TabBar(
    controller: _controller,
    tabs: [
      ...
    ]
  )

Will not look exactly as you want, but will give underlined indication to unselected tabs.
