How to display keyboard with only numbers?-CodePudding

I want to display keyboard with only numbers, not Operators or any other symbols in keyboard. I tried filter output already using inputFormatters in textfield.

CodePudding user response：

You will need to add inputFormatters & keyboardType properties to enable keyboard with number inputs only to your TextField widget.

inputFormatters: <TextInputFormatter>[
            WhitelistingTextInputFormatter.digitsOnly,
          ],
          keyboardType: TextInputType.number,

CodePudding user response：

if its in a TextField use this :

 keyboardType: TextInputType.number,
  inputFormatters: [FilteringTextInputFormatter.digitsOnly],

or you can use this :

 keyboardType: TextInputType.phone,

also you can check this package

check this package numeric_keyboard

Use keyboardType property of TextField

keyboardType: TextInputType.number,
            inputFormatters: <TextInputFormatter>[
              FilteringTextInputFormatter.digitsOnly
            ],

TextField(  
   keyboardType: TextInputType.number,  
   inputFormatters:<TextInputFormatter>. 
   [FilteringTextInputFormatter.digitsOnly]  
   decoration:InputDecoration(labelText: 'Number')
),
