highlight abstract method
- Object? color,
Prints the text associated with this span in a user-friendly way.
This is identical to message, except that it doesn't print the file name, line number, column number, or message. If length is 0 and this isn't a SourceSpanWithContext, returns an empty string.
color
may either be a String, a bool, or null
. If it's a string,
it indicates an ANSI terminal color escape that should
be used to highlight the span's text (for example, "\u001b[31m"
will
color red). If it's true
, it indicates that the text should be
highlighted using the default color. If it's false
or null
, it
indicates that the text shouldn't be highlighted.
This uses the full range of Unicode characters to highlight the source
span if glyph.ascii is false
(the default), but only uses ASCII
characters if it's true
.
Implementation
String highlight({Object? color});
