Can Line Chart show peak value?

hi , just like the following pic, can i use line chart mark peak value? thanks

Start by reading the current line-chart API and rendering behavior in the fl_chart repository. Clarify whether “peak” means a global or local maximum, how ties and changing data should behave, and what visual marker is expected; the issue is done when that behavior is agreed, implemented, and covered by relevant chart tests.
