Answer 1

使用颤振的TextSpan

Text _myText;
/*set _myText.text to whatever text you want */
RichText(
  text: TextSpan(
    text: 'Hi',
    style: DefaultTextStyle.of(context).style,
    children: <TextSpan>[
      TextSpan(text: _myText.text, style: TextStyle(fontWeight: FontWeight.bold)),
      TextSpan(text: 'how are you')




],
  ),
)
