Add a prefix to every line in a multiline Text Input in Flutter?
问题 I wanted to know if there was a way of adding a prefix (like "- ") to every line in a multiline Text Input in Flutter. For example: Hello World! Would become: -Hello -World! This is my code: TextField( maxLines: null, controller: _elementsController, textCapitalization: TextCapitalization.sentences, style: TextStyle( fontSize: 18.0, ), decoration: InputDecoration( contentPadding: EdgeInsets.all(0.0), labelText: 'Elements', ), ), 回答1: U can add a - everytime a new line is created. Add this in
