A Dart/Flutter package for easy validation.
I few days ago I published my first package: https://pub.dev/packages/verifyIt's a pure Dart package to do validations. Validations can be created in many ways and are easy to combine.I also think it's a great fit for validating bloc states for example.The API is very functional and flexible all done with extensions and typedefs. Give me your thoughts about it!

Does flutter optimize the build performance when build method called again on stateful widget by building changed components or it builds everything again?
Should I keep my stateful widgets too segregated to improve performance or flutter does that automatically?

Some small Questions
Hello Guys,I'm very new to Flutter / Dart or Mobile programming in generell, but worked as a C++ Dev for some time during University (just for some Background).I'm trying to build a small game in Flutter to get the hang of it and as of now i got some small questions, where i think only some keywords and ideas will guide me in the right Direction.This is my App so farIn the Top i am using a Container with RichtText and some Styling for some Game Information. I would like to have the gray Information oriented to the left, and the Red information to the right, but still in the same Line. What would be the easiest way to do so ?Bottom Side you can see a horizontal ListView consisting of FieldWidgets (own Class). In those Widgets id like to have the Text which u can see right now moved to the top left corner (with some padding) and then an Image of a Dice or a invisible placeholder in the center where the text is at the moment. Here the question is also about the alignment options, what would be the easiest way to do those two alignements. (The Field right now is a Container, i thougt about doing it with columns, but i could get it to work how i wanted it)This one is probably the most complicated: I'd like to be able to tap on the Information in the Top of the Screen and open a little Popup Dialog(?) where u see more information. In the same style id like to be able to press on the Fields in the bottom List and see another Popup. This one has different Content, precisly id like to have a own Widget (some kind of "picker") and a Confirm Button. On both those popups id like the popup to close if u press anywhere other then the popup.I hope those points where somewhat clear. I could add some source or further explanations if that helps.Thanks a lot in advance :)

GoalI'm building an iOS app using flutter for frontend, and C/C++ as backend. They must interoperate through FFI, which is a language binding scheme through C dynamic libraries. I intend to submit it to iOS App Store.ProblemsThe Dart FFI sample on accessing C-struct works on macOS through dynamic liking and binding. Now dynamic linking is technically possible on iOS according to Xcode 9 - No option to create dylib project iOS, however, it's unclear to me how to ship the app to AppStore, because dynamic linking is not allowed according to Apple Guidelines Section 2.5.2.2.5.2 Apps should be self-contained in their bundles, and may not read or write data outside the designated container area, nor may they download, install, or execute code which introduces or changes features or functionality of the app, including other apps. Educational apps designed to teach, develop, or allow students to test executable code may, in limited circumstances, download code provided that such code is not used for other purposes. Such apps must make the source code provided by the Application completely viewable and editable by the user.Quite a few SO questions confirm this problem, such as:can I use dynamic library(shared object) in my iphone app?Will Appstore reviewers allow us to use dynamic library in iOS8?QuestionsAs of the date when I post this (2020), does this say that I could never ship an app using this architecture to App Store?Is it possible that I static link my C/C++ code into a single binary of a flutter app? Take Unity as an example, their iOS plugin system recompiles the plugin into native app. If flutter has a similar mechanism, how?
