I had a string as below
String str = "Dart remove empty space ";
- To remove empty space from all occurences of the
string
folow below steps. - loop through the characters of the string and check for the
white space
. -
If found white space at particular index replace the character as below syntax.
for (int i = 0; i < str.length; i++) { if (!str[i].contains(' ')) { stringAfterRemovingWhiteSpace = stringAfterRemovingWhiteSpace + "" + str[i]; } }

Below is the sample example on how to remove
white space
import 'package:flutter/foundation.dart'; import 'package:flutter/material.dart'; void main() { String str = "Dart remove empty space "; String stringAfterRemovingWhiteSpace = ''; for (int i = 0; i < str.length; i++) { if (!str[i].contains(' ')) { stringAfterRemovingWhiteSpace = stringAfterRemovingWhiteSpace + "" + str[i]; } } print(stringAfterRemovingWhiteSpace); }
