Wait until map is completely initialized

[Christian]

Is there a way to have my app wait until the map is loaded? Whenever i click something or refresh the state before it is loaded it gives me the error below. I would like to have a loaded screen that waits for this to initialize.

The following LateError was thrown building FutureBuilder<_ShapeFileData>(state: _FutureBuilderState<_ShapeFileData>#b46b4):
LateInitializationError: Field 'initialSelectedModel' has not been initialized.

Hi Christian,

Greetings from Syncfusion. We have analyzed your query based on the provided error stack trace and we suspect that you have initialized the selected index value as a type late for initially no data was selected. This is the reason you get the issue, so we recommend you avoid initializing the selected index type as late and assign the selected index value -1 which denotes no data was selected at initial rendering. We have attached the demo sample below for your reference.
