Parameter fontSize causes widget to crash

[gseront]

Parameter fontSize of MapBoxPlaceSearchWidget is a String but is used in a context where a double is expected.
This causes a crash of the widget if the parameter is used:

type 'String' is not a subtype of type 'double?'

When the exception was thrown, this was the stack:
#0 _MapBoxPlaceSearchWidgetState._searchInput (package:mapbox_search_flutter/src/map_box_place_search_widget.dart:160:37)
#1 _MapBoxPlaceSearchWidgetState.build (package:mapbox_search_flutter/src/map_box_place_search_widget.dart:110:18)
#2 StatefulElement.build (package:flutter/src/widgets/framework.dart:4792:27)
#3 ComponentElement.performRebuild (package:flutter/src/widgets/framework.dart:4675:15)
#4 StatefulElement.performRebuild (package:flutter/src/widgets/framework.dart:4847:11)

I'd happy to correct it myself (I already did it in my own project) if you give me access.
