I have a list of customized icons to my app, it comes like below setted as IconData, note codePoint (0xe931).
IconData angry_face = IconData(0xe931, fontFamily: _fontFamily);
There's nothing wrong with that, but I've some cases where I need this icon as Unicode string to be used as a text. It should be done just like:
// It works too
Text('\ue931', style: TextStyle(fontFamily: _fontFamily));
The problem is:
I don't wanna use this code "by hand" because this icons are changed constantly by designers team and sometimes it changes its code messing up my app icons. What I need to do is get the icon object and parse it to the Unicode string, so I can use it with a Text widget.
I thought that would work to get programmatically that code and just use it, but it don't:
var iconcode = iconData.codePoint.toRadixString(16);
var result;
// Error: An escape sequence starting with '\u'
// must be followed by 4 hexadecimal digits or
// from 1 to 6 digits between '{' and '}'
result = '\u$iconcode';
// Just a simple string
result = '\\u$iconcode';
In few words: How can I parse programmatically int codePoint to a valid Unicode string?
final result = String.fromCharCode(iconData.codePoint);
