A form package providing Dart streams.

The most popular and stable form package for Flutter is definitely flutter_form_builder. However, it's design is event-driven. It solves the issue with mainly onChanged and similar callbacks.
This design has an inherent issue: It doesn't incorporate with modern stream-driven approach.
Since it doesn't get along well with streams, it will especially lead to various issues when you want to especially use a state management solution (mainly Bloc). That's because modern state management is mainly built upon streams.
I opened up this issue to explain that the library needs to incorporate with streams because I mainly wanted to integrate flutter_form_builder with bloc at that time as I was working on a project.
Not only that, I've also tried to implement it myself. Then I have realized that the whole package needed to be refactored from the very beginning, which is a heavy take on an existing and considerably-large project such as flutter_form_builder.
At the same time, I was looking for a 3rd-party solution that works well with streams, but there wasn't any good existing solution out there. For example, there's flutter_form_bloc, but it messes with raw material design that Flutter provides, which breaks visual consistency.
That's why I have created streaming_forms. A Flutter form package that specifically plays well with streams, so that you can listen to events asynchronously.
Currently, the package is in its alpha phase. There will be some design decisions on the API. The current goals are these:
- Work with asynchronous events provided by streams instead of event handler callbacks so that the devs can use it with their state management solution
- Add upon, but not change, the built-in form solutions of Flutter so that the users familiar with it can migrate easily or create forms without extra required knowledge
- Add a built-in validation logic
- Work with Bloc
❗ In order to start using this package you must have the Flutter SDK installed on your machine.
