If you have some implementations and generated files that you do not want to include in test coverage. You can add them in settings under `dart.coverageExcludePatterns`. Available in v3.118 VSCode Dart extension.

In the Flutter VSCode extension v3.118, you can see widget previews directly in the IDE. This feature is still experimental, so you must enable it manually and switch to the master channel of Flutter. Hopefully, it will soon be polished and become part of the stable version!

If you use a monorepo, you can run Dart linters and AI agents across multiple packages and apps Useful use cases: - documentation - unified coding style - refactoring with the help of AI - adding new linter rules with a fix available - searching for pitfalls/explanations in code

A couple of ways you can automate a monorepo with multiple packages/projects with Melos: - running build runner - testing unit tests/integration tests - generating API endpoints - creating licensing files for export

A Flutter monorepo simplifies developing apps/packages on a shared foundation Code/dependency changes propagate across the codebase in the analyzer. It forces you to maintain apps while you are making breaking changes. With a pubspec workspace, you can do the following:

Navigating directories can reduce friction when solving problems. I still recall discovering the `cd -` command, which allows you to toggle back to the previous directory in the terminal. Tools like zoxide are better, but for simple tasks, it remains relevant.

If you build a large app or work at a company, you likely end up splitting parts into packages and using custom tags for them. In Dart 3.9/Flutter 3.35.0 and higher, you can now parse the tag and deviate versioning from it, similar to other packages.

With Dart 3.9 / Flutter 3.35.0 and higher, you can apply a switch on the type linter rule. Avoid using runtime types if pattern matching is available. If classes change their hierarchies, it can lead to weird bugs.

local_auth_darwin now supports more granular handling of unhappy paths at version 1.6.0 You can now handle disabled biometry, user fallback, and authentication cancellation by extending error codes. The codes are not defined at local_auth in the meantime.

I see many people recreating the HTTP client whenever it is needed. Each new client can open new network connections, which is slow, resource-intensive, and will slow down other requests. Create one client and use it everywhere.

My favorite pattern for clean, accessible logging. Define this mixin once, and get a consistent logger instance in any class. No more manual instantiation.

Your logs are a mess because you: - Only use print methods - Have no severity levels - Can't filter by category If your logging strategy was strong enough, you wouldn't waste hours scrolling through chaos.

On the client device, never print: - passwords or credentials - API keys, secrets, or certificates - session tokens - any personal data - any bank account details
