We use Xamarin since few years but it’s important to be open minded on what happens in the mobile market. For this reason we want to invest into new Google fwk Flutter.
In short, Flutter advantages are :
Fast Development :
Paint your app to life in milliseconds with Stateful Hot Reload. Use a rich set of fully-customizable widgets to build native interfaces in minutes.
Expressive and Flexible UI :
Quickly ship features with a focus on native end-user experiences. Layered architecture allows for full customization, which results in incredibly fast rendering and expressive and flexible designs.
Native Performance :
Flutter’s widgets incorporate all critical platform differences such as scrolling, navigation, icons and fonts to provide full native performance on both iOS and Android.

But that’s the theory and a gap always exist.
Internship will be split in these parts :
 
1.       Analyze the solution ( limitation, market penetration, coming feature & release, … )
2.       Present the solution to mobile experts to share your work
3.       Create a Sample Application
4.       ​Do a demo of your application and explain advantages and disadvantages
