[@3mro_coding]

Did you show ur localhost as https how? Adding self signed ssl? To the vhost?

[@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....
