In my Flutter log I\'m constantly getting this messages(just with some different numbers):
Background concurrent copying GC freed 153040(3MB) AllocSpace objects,
Don't mean to bump this question/answer but, in case is useful for others nowadays ... Another reason for this message to appear is when the logic of the application enters into an infinite loop (e.g. a cursor that never moves to Next record, etc). Eventually the GC starts doing too much work under such conditions.
