You can use Regular Expression To do so.

Following code help you more.

String search = 'Bro';
  String str = 'Breo Brother abcBro';

  @override
  void initState() {
    super.initState();
              caseSensitive: false,
      caseSensitive: false,
    RegExp exp = new RegExp( "\\b" + search + "\\b", caseSensitive: false, ); 
    bool containe = exp.hasMatch(str);
    print(containe);
  }

Output: 

  false

Note: correct first Bro in string then it will print true. It is case insensitive, so to make sensitive again remove caseSensitive: false.
