[@techhublearn1]

Hi Andrea sir can you suggest some interesting college project using flutter.

[@LinJheYi]

Unfortunately Tip #2 is wrong, Future.wait didn't run Futures concurrently, it just run them sequentially in current isolate/event loop, and give you all result after every Future is finished. If you want real concurrency, you should spawn new isolates.
For example:
void main() async {
await Future.wait([
Future(() { for (int i = 0; i < 5; i++) { print(i); } }),
Future(() { for (int i = 0; i < 5; i++) { print(i); } }),
Future(() { for (int i = 0; i < 5; i++) { print(i); } }),
]);
}
It'll print 1,2,3,4,5,1,2,3,4,5,1,2,3,4,5, instead of 1,1,1,2,2,2....
