The future and async/await is used for asynchronous programming in Dart. We will explore these further more but let’s us know the overview of asynchronous programming.
synchronous programming is the method written to perform one task at a time. In programming languages when the function depend’s on the other function’s output, it has to wait to finish the execution of that function. The program is essentially stopped until the function finishes its execution. It means the one program can get executed at a time. This waste a resourcesto do other task rather than available ideal sit.
To overcome this issues ,Asynchronous programming concept comes into play. It also takes one execution at a time but does not wait to finish the execution to move forward.
Dart uses future and async/await for asynchronous programming. You can learn more about it.
