Thousand separator in flutter

Question

Is there a way to make a thousand separator when typing numbers in a TextFormField in flutter? This is my TextFormField

child: TextFormField(
 decoration: InputDecoration(
     border: const OutlineInputBorder()),
 keyboardType: TextInputType.number,
),

Answer 1

First add intl flutter package

dependencies:
  intl: ^0.16.1

Now use NumberFormat

 var formatter = new NumberFormat("#,###");
  print(formatter.format(1234)), // this will be: 1,234
