How do I unload an event loop in Dart? It is quite a common situation for us to have APIs like Future<List<T>>.

Imagine a method that returns a list of users. What you do there is parse the json into a dart list and then somehow convert it into a typed list of models. This conversion to models can be done lazily. Just change the API to Stream<T> and you will get the idea. You can put all the elements in the event loop to process them asynchronously.

Here is the link to the working flutter app, which gives you an example of how to do this:

Today published a post about Dart GC. I wrote about the garbage collection process and the tricks it employs.

Today I learned an interesting algorithm for finding the majority element.

The Boyer-Moore majority algorithm is a popular algorithm for finding the majority element in a list of integers. The majority element in an array (or list) is an element that appears more than n/2 times where n is the size of the array.

Here's a simple way to describe the Boyer-Moore Voting Algorithm:

1. Start with an initial candidate and a counter set to 0.
2. Iterate over the list of numbers.
3. For the current number: If the counter is zero, set the current number as the candidate.
4. If the current number is the candidate, increment the counter. Otherwise, decrement the counter.
5. The candidate will be the majority number.
