A few days ago I decided to create two scopes for the starter. Theme and Locale scope, so you can switch the themes, create custom ones without any effort. Also you can switch languages in the app.
I believe it would be really beneficial to have these scopes😪

Is it possible to send non-primitives between Isolates?
Anonymous Quiz
39%
Yes, you can send different objects between Isolates in the same Isolate Group.
61%
No, this is not possible because only primitives can be sent via SendPorts.

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.

Should BLoC know anything about its consumers?
Anonymous Quiz
10%
Yes. It addresses their requirements and may have states such as ShowDialogState.
90%
No. Its duty is to do business logic and be consumer-agnostic.

Many people follow the official Flutter channel, and there is a well-known rubric called Observable Flutter, which invites the most renowned contributors and open-source activists.
Recently, Dane Mackier, the author of Stacked, presented the library and I aim to provide an overview of his brainchild. My objective is to inform and increase awareness of the architecture and principles presented, rather than critique.
Read about it in my article. This should be interesting for folks who don't use stacked as well.
