Form validation in Flutter
Validating user input before submission is a good thing to do if you want to improve UX and security. Because everyone can make mistake, your users too. You wouldn't like if user mistakenly typen his email johndoecorp.com and you need to contact him. You need to guess if correct email address is john@doecorp.com or johndoe@corp.com (I actually faced with this sort of issue with phone number field). So It's nice to have form fields validated before submission.Doing validation on client side also has another pro. It improves user experience. User don't have to wait 1-2 seconds to receive error message from the server.You need to verify fields on the server side too! Otherwise your app might be spammed with fake data. Why?I made a dart / flutter package to create different validation logics for example: string length validators, email, phone number, url, ip, and many more coming. Here's a simple code that validates if input is a valid email address and length is less than or equal to 50 characters.
Repository: https://github.com/TheMisir/form-validatorI need help for adding more languages to this package. You can simply duplicate lib/src/i18n/en.dart file and translate messages to your language.Language files looks like that:

Can you save/load a screens widget tree to/from JSON
I have this idea for a kinda note taking web app, specifically for D&D DMs. But there are a lot of different techniques and ways to store information. So had the thought that it would be cool to create a note taking app, kinda like oneNote, but users can create templates for the pages. But not sure how I would save the templates that the users create so that it saves the widget tree and can build the screen from that template.Is it possible to export a widget tree as a json file and have all the fields saved that way. Or is there another approach to where I could create a page creator for the users (kinda like wordpress or wix) and then they can save that page as a template and use it.

Recommended platform to get a flutter dev to finish a project
I have an app that due to time constraints I haven't been able to finish myself and I'm looking to get a flutter dev to pick up where I left off and finish my app. I'm looking for a platform that allows me to post my needs and get quotes from flutter devs. What platform do you recommend? I hope I'm not braking rule 6, since I'm only asking for a platform. Thank you!
