I have 3 button in a row like these : button 1 button 2 button 3
and I want just the text of selected one bolded. for example : button 1 button 2 button 3
what's the best and easiest way?

CodePudding user response：

Create a variable to hold the current button thats selected. Then based on that you can switch the fontWeight like the following

int selectedButton = 0;

Row(
 children:List.generate(3, (index) {
   return InkWell(
    onTap:(){
      setState((){selectedButton = index;});
    },
    child: Text("button $index", style: TextStyle(
     fontWeight : selectedIndex == index ? FontWeight.w900: FontWeight.w400,
    ))
   )
 })
)
