At DCM, we understand the importance of maintaining a high-quality codebase, especially in a project as widely used as the Wolt Modal Sheet package. This package provides developers with a powerful tool for implementing responsive modals with multiple pages, smooth transitions, and scrollable content within Flutter applications. However, as projects grow and evolve, ensuring code consistency and catching potential bugs early becomes increasingly critical, particularly when maintaining an open-source project that receives multiple pull requests from different contributors.

Before we start, we'd like to mention that we offer a free OSS license for Dart and Flutter open-source packages. Check out our pricing and contact us by clicking the "Looking for OSS license?" button.

In this guide, we will walk you through the process of integrating DCM into the Wolt Modal Sheet package, covering everything from the initial setup to configuring CI pipelines and addressing code issues.

Today we’re excited to announce the release of DCM 1.21.0!

Code reviews are integral to the software development lifecycle, crucial in maintaining code quality and promoting team collaboration. In this blog, I want to explore the importance of code reviews, tools, and practices to enhance the code review process and emphasize best practices specific to Dart and Flutter development. We will also discuss advanced concepts like "Shifting Left" to integrate reviews earlier in the development cycle, minimizing issues before they propagate.

There's a prevailing myth in software development that less code is always better. While concise code can benefit specific contexts, it doesn't necessarily equate to better code. Code quality, maintainability, and readability are often far more important than simply being less.

This article will explore why writing more code can often lead to better software, especially in Dart and Flutter applications. We'll focus on clarity, modularity, flexibility, robustness, and error handling. We'll also discuss the drawbacks of "magic" code and the importance of linting and rules in maintaining code quality.

Today we’re excited to announce the release of DCM 1.19.0!

This release includes 9 new rules (4 for Riverpod), proper support for codegen packages by the check-dependencies command, new summary output to sdterr for various reporters, new visualization of the statically resolved widget trees for analyze-widgets, new fix type for removing unused files (moved from check-unused-files), documentation updates and other DX improvements! 🚀

Maintaining consistent and high-quality code is necessary in the fast-paced software development world, especially in Flutter and Dart projects, as they are known for being speedy tools. Continuous Integration (CI) has emerged as a crucial practice that helps development teams achieve this goal. CI provides rapid feedback by integrating code frequently and automating various aspects of the development process, allowing teams to identify and rectify issues early.

This article explores the significance of CI in enforcing code quality and consistency, the role of lint tools, especially DCM, and practical examples of integrating these tools with CI pipelines.

Today we’re excited to announce the release of DCM 1.18.0!

This release includes 8 new rules, improved "New Version" notifications, new grouping option for IntelliJ plugin, automatic DCM version detection by the "setup-dcm" action and general UX improvements 🚀.

On any real-world Flutter project (but any project, really...), you want to run an analyzer and a linter at some point to ensure your quality matches the baseline your team agreed on. If you've been following me for some time, you might know that I love a promising CI/CD pipeline (heck, I even wrote a series on the topic 🙃). I always recommend running these checks in your CI pipeline.

Today we’re excited to announce the release of DCM 1.17.0!
