Remove the spaces between the closing and opening tag in html with Dart

I followed some discussions in StackOverflow to get help to resolve my issue specific to Dart. I used the regex command to remove the place between the closing and opening tags in HTML. But it did not work for me.

Code

import 'dart:html';
void main() {
 var result = '<div><div><ul> <li>Chair</li>  <li>Table</li>  <li>Fan</li></ul><div></div>'.replaceAll(RegExp(r'/>\s+</gim'), '><');
  print(result);
}

Actual Result

<div><div><ul> <li>Chair</li>  <li>Table</li>  <li>Fan</li></ul><div></div>

Expected Result

<div><div><ul><li>Chair</li><li>Table</li><li>Fan</li></ul><div></div>

I would like to know what type of change I need to do in my regex to get the expected result.

Thanks, in advance.

>Solution :

Change to:

.replaceAll(RegExp(r'>\s+<'), '><')
