Null check operator used on a null value; #0 State.context (package:flutter/src/widgets/framework.dart:916)#1 _TooltipState._createNewEntry #95851
Description
Unfortunately i can not give you any reproducible code because this error is caught by runZonedGuarded(error; stackTrace) method and reported to application's server. I've tried to recreate it myself but i have no idea how it appears. I notice these error reports since flutter 2.2.3

This is the way i make tooltip visible:
final GlobalKey<State<Tooltip>> _toolTipKey = GlobalKey<State<Tooltip>>();
final dynamic tooltip = _toolTipKey.currentState;
if(mounted && _toolTipKey.currentState?.mounted != null) {
tooltip?.ensureTooltipVisible();
}
