I've got a screen with yandex map and sliding up panel with many input texts inside and while Im operating with it (e.g. typing text into textfields) app may crash with an SIGABRT signal but may not, it only occurs when I have my sliding up panel open.

It often occurs when I click button too much but not necessarily. Seems like the problem is not inside database connection because even if I make onPressed method return null it keeps crashing randomly.
