how to make text-based rpg flutter code example

Example 1: Flutter new paragraph text

         child :  Text('''
                          Text1
                          Text2
                          Text3''',maxLines: 20, style: TextStyle(fontSize: 16.0 ,fontWeight:FontWeight.bold,color: Colors.black) , )

Try giving your Row a CrossAxisAlignment of CrossAxisAlignment.start. Is this what you had in mind?
