Is there any plugin for Flutter Framework? If it does not exist, has the Here Team plans developing an official plugin?

I implemented a working prof-of-conept of a HEREMaps Flutter plugin. However, it shares the same limitations as the first version of Google Maps that has been using a Surface-Draw approach. In detail: the HEREMaps plugin currently relies on placing platform overlays on top of a bitmap snapshotting widget for creating the illusion of in-line compositing of HEREMaps views with Flutter widgets. This works only in very limited situations where - the widget is stationary - the widget is drawn on top of all other widgets within bounds - touch events within widget bounds can be safely ignored by Flutter
Currently Flutter does NOT allow to create a native (Maps / any UI) plugin without these limitations. Even the Google Maps plugin from Google itself works only on Android as of now.
Once these limitations are removed, I can create a fully featured HERE Maps plugin :-)
Its not that hard to use platform code within Flutter. However, I would prefer a direct C++ binding to avoid the Objectiv C / Java to Native bridge overhead. Ideally, the DART Code bindings could be autogenerated from C++ code.
I am sure if enougth developers are asking for a HERE Maps Plugin for Flutter, HERE will provide one. Currently Flutter has some limitations that makes it impossible to provide a Maps plugin that does not have the limitations I mentioned. For sure, that is one techncial reason HERE has not provided an official plugin yet. Btw. I am not aware of any working maps plugin for Flutter without these limitations.

Here doesn't provide any separate support for Flutter Frameworks nor have any plugins yet. But you should be able to use our Android/iOS SDKs in your framework. https://developer.here.com/develop/mobile-sdks
