RichText widget

RichText(
  text: TextSpan(
    text: 'Hello ',
    style: DefaultTextStyle.of(context).style,
    children: const <TextSpan>[
      TextSpan(text: 'bold', style: TextStyle(fontWeight: FontWeight.bold)),
      TextSpan(text: ' world!'),
    ],
  ),
)

Seems like you receive some Markdown formatting from server (?)

So you can use https://pub.dev/packages/flutter_markdown to parse it and render it

Markdown(
    controller: controller,
    selectable: true,
    data: 'Hey *there*',
)
