Note, this is called flow-sensitive typing (also called type narrowing) and I think that typescript does it.

A model checker can do that!

Other techniques are also possible

(Here I could link a lot of things, I just selected two Rust projects to illustrate)

This works better if you are able to provide contracts in your API that says which guarantees you provide. Alternatively, asserts are useful too.

You might be interested in the Prusti project, which statically checks for absence of reachable panics, overflows etc. It also allows user-defined specifications such as pre and post-conditions, loop body invariants, termination checking and so on.

This is called refinement types and prusti might be the project you saw.

But there's also a lot of exciting work around formal verification like Prusti.

Efforts: seL4, Project Everest, the Prossimo project of the ISRG, Let's Encrypt, and Prusti for the Rust language

Wow that sounds really cool! I'm not an expert but does that mean that one day you could implement dependend types or refinement types in Rust as a crate ? I currently only know of tools like: Flux Creusot Kani Prusti

Gerrit is optimized for in-house work lead by engineers who would rather be using Subversion. ("Subversion merge isn't worth using so I don't see why we need it.") It tends to be hostile to community contribution: outsiders get a second-class experience, so if community participation is your goal it's a bad choice.

First off, Flutter uses Dart for its codebase. This means that the Dart programming language is used to develop the UIs, logic, and functionalities of applications and software built with Flutter.

The methods and other important information are documented in detail here. I have been exploring it and received some advice from Norbert 🙌.

Flutter is written in Dart, and its C interop story isn't strong (all functions that have to be callable from C have to be specifically annotated, and it doesn't support named parameters, which are used all over the place in Flutter). Here is my ticket for that.
