Using multiple autoComplete Textfield in same widget tree cause global key exception

[felixmccuaig]

Umm yeah, this should most definitely be possible. Just give each autocomplete text field its own global key and you'll be fine.

GlobalKey<AutoCompleteTextFieldState<String>> key1 = new GlobalKey(); //Key for textfield one GlobalKey<AutoCompleteTextFieldState<String>> key2 = new GlobalKey(); //Key for textfield two

I tried this but it throws an exception

This line states multiple widgets are using the same key. here seems like a good overview of how globalkey works in Flutter.

thanks,
I am actually using it in a diff way, i created another widget on top of autoComplete widget, due to this i am not able to pass multiple global keys, since doing GlobalKey<AutoCompleteTextFieldState> key1 = new GlobalKey() 2 times also create same instance of Globalkey.

If you're subclassing the AutoCompleteTextField, you'll need to implement the necessary implementations.
