How can I convert text with spaces to single space in TextFormField?

How can I convert text with too many spaces to single space? For example name: "Brad Pit" there is only one space between first and last name but user can write "Brad (4 space) Pit" with too much space. How can I reduce this to single space in TextFormField?

Code:

void main() {
  var name = 'Pratik      Butani';
  print(name);
  print(name.replaceAll(new RegExp(r"\s+"), " "));
}

Output:

Pratik      Butani
Pratik Butani

Explanation: Here I have used RegExp which will take continue spaces using \s+ and It will be replaced by one space.

You can this demo on DartPad

Do let me know if you have any confusion.

In Dart u can use:

print(yourString.trim())

to convert text with too many spaces

and u can try this

String name = 'Brad    Pit ';
print(name.replaceAll(new RegExp(r"\s+"), ""));

To reduce multiple space to a single space Please refer to this answer https://stackoverflow.com/a/1981366/9414608

Also you can prevent users from adding spaces in the TextFormField by using inputFormatters
