Amazing..thanks for the reply. I am newbie to dart & kotlin (love both coming from Java) but never knew you can use dart with kotlin. I am thinking of using kotlin on backend to create RESTful api for angulardart 4 front end. Flutter looks good for mobile apps. I got deployment ready "Tip calculator" app in first hour of studying flutter for IOS & android (no prior knowledge of flutter or dart) Can you tell me which UI library you're using for angular dart projects? I don't see many libraries apart from official angular_components 0.6. My biggest worry is adoption of dart on front end as I hate typescript & JS even more after doing a little prototype in angular dart. If possible please share your experience on kotlin to dart conversion project in another blog...interesting for sure
