Flutter TextField input only decimal numbers

Question

I want to input only decimal number in TextField in Flutter. I tried below code but that\'s not working. It allows alpha (a-z) and special characte

Answer 1

I am using this code and it's giving different results , on some phones it shows only numbers and on others it shows dashes and other chars , so it depends on the launcher or something like that i guess, in iPhone i guess it will show the correct keyboard ( i have tried on iPhone 7s plus).

the inputFormatters will allow only numbers so you will get what you want.

   TextField(
     textAlign: TextAlign.start,
     keyboardType: TextInputType.numberWithOptions(decimal: true),
     inputFormatters: [
                          FilteringTextInputFormatter.digitsOnly
                       ],
   ),
