As a Flutter developer, I'm always excited about new features that make my code cleaner and more efficient. And Flutter's recent addition of Future.wait is definitely a game-changer!
Previously, I often found myself writing code that awaited multiple futures, like looping through async calls and waiting for each result before adding them to a list. This could get messy and hard to read.
Future.wait simplifies this process by allowing me to await a list of Futures and return a single future that completes once all the individual futures have finished. The returned data is a list of the results from each future, in the same order they were provided. Plus, if any of the futures fail, the entire Future.wait fails, making error handling much easier.
Another cool aspect is that I can add futures to the list either all at once or one by one. Regardless of the approach, all the futures kick off simultaneously. This significantly improves code readability and ensures that my total waiting time is only as long as the slowest future, rather than the sum of all futures.
Overall, Future.wait is a fantastic addition to the Flutter developer's toolkit. It helps write cleaner, more efficient code and saves valuable development time.

I hope this helps! Feel free to adapt this post to include your own specific experiences with Future.wait.
Instead of waiting for the sum of the wait times across all of the futures, only wait for the longest future! 🔮

2wThere's also the .wait extension method if you need different types! You can do it like this to have the values separately instead of a list of values of the same type. final (value1, value2) = await (future1, future2).wait;
