How to create number input field in Flutter?

Question

I\'m unable to find a way to create an input field in Flutter that would open up a numeric keyboard. Is this possible with Flutter material widgets? Some github discussions

For those who need to work with money format in the text fields:

To use only: , (comma) and . (period)

and block the symbol: - (hyphen, minus or dash)

as well as the: ⌴ (blank space)

In your TextField, just set the following code:

keyboardType: TextInputType.numberWithOptions(decimal: true),
inputFormatters: [BlacklistingTextInputFormatter(new RegExp('[\\-|\\ ]'))],

The simbols hyphen and space will still appear in the keyboard, but will become blocked.
