使文字的特定部分在颤动中可单击 [英] Make specific parts of a text clickable in flutter
本文介绍了使文字的特定部分在颤动中可单击的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想使文本的一部分变为可轻敲,以便可以在其上调用一个函数。我也想控制可点击文本的样式。在最佳情况下,我还可以将可点击区域的大小增加到例如42px。
我已经研究了flutter_linkify和linkify,但这不是我想要的。我很好奇是否已经在flutter库中建立了一个包,甚至内置了一个包。
解决方案
使用
I want to make a part of a text tapable so I can call a function on it. Also I want to have control over the style of the tapable text. In the best case I can also increase the size of the tapable area to for example 42px.
I already looked into flutter_linkify and linkify, but that's not what I want. I'm curious if there's already a package or even built into the flutter library.
解决方案
Use RichText with TextSpan and GestureRecognizer. With GestureRecognizer
you can detect tap, double tap, long press and etc.
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"');
}),
],
),
);
}
