How to Remove All Whitespace Characters from a String in Dart ?

Answer

To remove all whitespace characters from a string in Dart, you can use the `replaceAll` method with a regular expression pattern.

✐ Examples

1 Remove Whitespace from "Hello World"

In this example,

We create a string variable str with a value of "Hello World".
We then use the replaceAll method with a regular expression pattern "\\s" to replace all whitespace characters (including tabs, spaces, newlines, etc.) with an empty string in str.
Finally, we print the modified string str to the console.

Dart Program

void main() {
  String str = "Hello World";
  String modifiedStr = str.replaceAll(RegExp(r'\\s'), '');
  print('Modified string: $modifiedStr');
}

Output

Modified string: HelloWorld

2 Remove Whitespace from "apple\tbanana\n cherry "

In this example,

We create a string variable str with a value of "apple\tbanana\n cherry ".
We then use the replaceAll method with a regular expression pattern "\\s" to replace all whitespace characters (including tabs, spaces, newlines, etc.) with an empty string in str.
Finally, we print the modified string str to the console.

Dart Program

void main() {
  String str = "apple\tbanana\n cherry  ";
  String modifiedStr = str.replaceAll(RegExp(r'\\s'), '');
  print('Modified string: $modifiedStr');
}

Output

Modified string: applebananacherry
