将RichText与TextSpan和GestureRecognizer一起使用。使用
GestureRecognizer它可以检测 点击 ， 双击 ， 长按 等。
Widget build(BuildContext context) { TextStyle defaultStyle = TextStyle(color: Colors.grey, fontSize: 20.0); TextStyle linkStyle = TextStyle(color: Colors.blue); return RichText( text: TextSpan( style: defaultStyle, children: <TextSpan>[ TextSpan(text: 'By clicking Sign Up, you agree to our '), TextSpan( text: 'Terms of Service', style: linkStyle, recognizer: TapGestureRecognizer() ..onTap = () { print('Terms of Service"'); }), TextSpan(text: ' and that you have read our '), TextSpan( text: 'Privacy Policy', style: linkStyle, recognizer: TapGestureRecognizer() ..onTap = () { print('Privacy Policy"'); }), ], ), ); }
