Couldn't access map object via same inherit class about blazorgooglemaps

First of all you should use map event to find when map is loaded. Check example in readme(front page)

OnAfterInit="@(async () => await OnAfterInitAsync())"

Second this is very bad. Component is redrawn each time any value changes and it will be trigered each time.

if (!firstRender)

Also you should try debug with edge application and see if any markers is added to markers.
In my opinion you should change and OnAfterInit event and it should work

@valentasm1 m1, thank you for the fast response. I implemented your suggestions but i still got the same problem.

Since i have the markers written out on the map, shouldnt they exist?
I did a Console.WriteLine(map) in the OnAfterInitAsync() method and in the method onFilterSelected. In the OnAfterInitAsync() method i find the object and get "GoogleMapsComponents.GoogleMap" written out and in the onFilterSelected method it writes out nothing.

It seems like i still have the same problem accessing the map object..

If i understand correctly it is not issue with accessing map. There is issue with Stack markers .
I think you should create github or zip solution that i could reproduce issue. You could make just part of not working. No need all solution.
Again i think this is not map issue, but something with lifecycle or business logic. Of course i could be wrong.

@valentasm1, I created a repo with the same problem: https://github.com/Essum13/GoogleMapsBlazorIssues.git
Wrote some comments inside the BaseClass.

(I removed valid google maps api key).

Thank you for you time preparing github. Now i get it.
Dont take anything personally. You inheritance is strange. I think i mixed up functionality. If two components inherit same base it doesnt mean they share same instance.
SearchComponent < MapBase
AND
Map < MapBase

You see. If you draw smth on map.razor then SearchComponent.razor < Map base doesnt know anything about it.
My suggestion is to create MyMapComponent where you bind Locations via [Parameter] property from parent component. Parent component have all info about locations and it changes then child will update automatically. Then on parent if you change Select control, then you already know info about locations.

My suggestion read this documentations. Especial part about child components which is relavant to you. It a bit hard to grasp so probably you will need to read several times and compare with other recourses.
