Just started to learn dart for flutter apps

@csesanthosh15 mainly documentation and sample apps, my friend @ng1905 helps me too

@AlexDeLarge at first I was a bit confused by the code style of dart, in java I always try to hold the code flat and avoid if statements in other if statements.

But what I learned since now is very interesting, for stuff I needed in native android app multiple hours of design, in Flutter its way faster.

And Flutter is exactly what I needed for my simple app, now I just need a mac for testing on ios :D
