xamarin.forms - TailTruncation when the label meets the limit of word wrap in Xamarin Forms -

in xamarin.forms tailtruncation mode labels works fine single lines of text.

we can force tailtruncation happen @ 2nd or 3rd or nth line, if know in advance lenght of text, using custom renderer one: depechie multilinelabel .

but need tailtruncation works when don't know in advance how many lines of text fit in label.

if height of label changes, , number of lines of text can fit in it, want tailtruncation happens @ end of available space. not @ line before , neither @ line after.

how can tailtruncation happens when text meets limit of available word wrap space inside label bounds?

is there custom renderer trick allows calculate number of lines fit inside bounds , set tailtruncation line number accordingly (on both ios , android)?

thanks in advance.
