defaultArgumentListTextRanges property
Pairs of offsets and lengths describing 'defaultArgumentListString' text
ranges suitable for use by clients to set up linked edits of default
argument source contents. For example, given an argument list string 'x,
y', the corresponding text range 0, 1, 3, 1, indicates two text ranges
of length 1, starting at offsets 0 and 3. Clients can use these ranges to
treat the 'x' and 'y' values specially for linked edits.
Implementation
List<int>? defaultArgumentListTextRanges;
