MaterialTextField choice is very slow with large data

[andy200486]

I'm using an MaterialTextField with InputType "Choice" to select a country. The display of the dialog box is very slow. I have an Enum with +/- 200 country (only string) to show and it takes (depends on the smartphone) 10-20 seconds.

Is there a solution to this problem ?

Thanks !

Hi, the current implementation of the dialog uses the BinableLayout feature, which I think has some performance issue during rendering. I'll try to update the layout to use the new CollectionView control.

Ok great, can you tell me when you've done the changes ? So I'll try.

Thanks !

Hi, can you validate this issue ?

It is extremely slow, at least show a loading symbol or something.

I'm also having this issue. Is there any update or workaround? For the moment I've gone back to using the default picker which has much better performance but does not look as good.
