BoxConstraints forces an infinite width

Question

I am getting an error when I add a row in column. I am getting following error:

I/flutter ( 6449): ══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═══════════════         


        

Answer 1

Reason for the error:

TextField expands in horizontal direction and so does the Row, so we need to constrain the width of the TextField, there are many ways of doing it.

1. Use Expanded

    Row(
     children: [
       Expanded(child: TextField()),
       // more widgets
     ],
   )
   

2. Use Flexible

   Row(
     children: [
       Flexible(child: TextField()),
       // more widgets
     ],
   )
   

3. Wrap it in Container or SizedBox and provide width

   Row(
     children: [
       SizedBox(width: 100, child: TextField()),
       // more widgets
     ],
   )
