Solution 1

Finally It worked for me

new TabBar(

          tabs: [
            _individualTab('assets/icons/bottom_nav/Home.png'),
            _individualTab('assets/icons/bottom_nav/Guys.png'),
            _individualTab('assets/icons/bottom_nav/Notes.png'),
            Tab(
              icon: ImageIcon(AssetImage('assets/icons/bottom_nav/Email.png')),
            ),
          ],
          labelColor: STColors.PRIMARY_COLOR,
          unselectedLabelColor: Colors.grey,
          indicatorColor: Colors.white,
          indicatorSize: TabBarIndicatorSize.tab,
          labelPadding: EdgeInsets.all(0),
          indicatorPadding: EdgeInsets.all(0),
        ),

Individual Tab Function

Widget _individualTab(String imagePath) {
return Container(
  height: 50 + MediaQuery
      .of(context)
      .padding
      .bottom,
  padding: EdgeInsets.all(0),
  width: double.infinity,
  decoration:  BoxDecoration(border: Border(right: BorderSide(color: STColors.LIGHT_BORDER, width: 1, style: BorderStyle.solid))),
  child: Tab(
    icon: ImageIcon(AssetImage(imagePath)),
  ),
);

}

Solution 2

To achieve small size separator you can use this.

Widget _individualTab(String imagePath) {
return Container(
  height: 50,
  width: double.infinity,
  decoration:  BoxDecoration(
    border: Border(right: BorderSide(color: STColors.LIGHT_BORDER,
        width: 0,
        style: BorderStyle.solid),
    ),
  ),
  child: Stack(children: <Widget>[
    Center(
        child: Tab(
          icon: ImageIcon(AssetImage(imagePath)),
        ),
    ),
    Align(
      alignment: Alignment.centerRight,
      child: Container(
        color: STColors.appBlackMedium,
        width: 1,
        height: 25,
      ),
    )
  ],)
);

}
