How does Atlas ensure Dart documentation is up to date?

Atlas reads your Dart source code directly using tools like lsp and read, ensuring documentation reflects the current implementation, not outdated specifications. This guarantees that your README describes what the Dart code actually does today.

Can Atlas verify Dart code examples in my README?

Yes, Atlas uses the bash tool to execute every Dart code sample within the generated README, confirming its functionality and accuracy. A sample that was never executed is considered a liability, so Atlas actively tests them.

What Dart tools does Atlas integrate with?

Atlas integrates with core Dart tools such as pub for package management, dart test for running tests, and understands pubspec.yaml and analysis_options.yaml files to contextualize your project.

How does Atlas handle sensitive Dart code or proprietary information?

Atlas can build its code index with local Ollama embeddings, keeping your Dart code off third-party servers. All Atlas tool calls are permission-gated against allow, ask, and deny rules for enhanced security.

Does Atlas change my Dart code without permission?

No, Atlas drafts a plan in a read-only agent and asks for approval before switching to a build agent. It computes a unified diff for every file edit, which you must approve before writing any changes to your Dart project.

How does Atlas find all public APIs in a Dart module?

Atlas uses the lsp tool's documentSymbol operation to enumerate the real exported surface of your Dart module, ensuring no public API is missed or invented in the documentation. This provides a complete and accurate API surface.

Can Atlas help with null safety migration in Dart?

Yes, you can ask Atlas to migrate your Dart project to null safety or add tests, reviewing the diff of the proposed changes before applying them. This helps maintain modern Dart code practices.

Document a Dart Module with a README in 2026 using Atlas

Atlas empowers Dart developers in 2026 to produce precise README documentation that reflects the current state of their code, not historical intent. By leveraging the lsp tool's documentSymbol operation to enumerate public APIs, reading implementations, and verifying code samples with bash, Atlas ensures every claim is traceable to the source. It integrates direct with the Dart toolchain, including pub for package management and dart test for verification.

How Atlas Generates Accurate READMEs for Dart Modules

Atlas generates precise README documentation for Dart modules in 2026 by directly analyzing source code, ensuring the output reflects current behavior rather than outdated specifications. It employs the lsp tool's documentSymbol operation to enumerate every public API export, guaranteeing comprehensive coverage of the module's surface area.

To document a Dart module, Atlas first uses the lsp tool's documentSymbol operation. This crucial step enumerates the real exported surface of the Dart module, ensuring that no public API is missed or invented in the documentation. Following this, Atlas utilizes the read tool to gather the implementation details of each export. To provide practical context, codebase_search is then employed to find how callers actually use these Dart exports in practice across the codebase. This approach ensures that the generated README for your Dart package, which might include a `lib/src/my_module.dart` file, is traceable to the source code. Atlas works effectively across pub packages and null-safe Dart code, understanding the nuances of the language to produce documentation that accurately describes what the code actually does today, rather than what it was intended to do a year ago. This method provides a robust foundation for creating READMEs that are always current and verifiable.

Integrating Atlas with the Dart Toolchain and Project Structure

Atlas integrates deeply with the Dart ecosystem, recognizing pubspec.yaml files to understand package structure and dependencies, a crucial step for accurate documentation in 2026. Before any operation, Atlas reads your libraries, pub dependencies, and analysis options to build a complete context of your Dart project.

For any Dart project, Atlas begins by running in a package containing a `pubspec.yaml` file. This file is central to defining a Dart module's identity, dependencies, and executables. Atlas then proceeds to read your Dart libraries, `pub` dependencies, and `analysis_options.yaml` to establish a comprehensive understanding of the project's configuration and code style. This deep integration means Atlas understands the context of your Dart code, whether it involves managing dependencies with `pub get` or ensuring code quality with `dart format`. When documenting, Atlas can quote real Dart signatures and real file paths, such as `lib/src/api.dart`, making the documentation concrete and specific to the Dart language. This ensures that the generated README is not generic, but truly reflects the structure and conventions of a Dart codebase, providing relevant information for any Dart developer.

Ensuring Safety and Review for Dart Documentation Edits with Atlas

Atlas prioritizes safety and developer control when documenting Dart modules, implementing a robust review process for every proposed change in 2026. Every Atlas tool call is permission-gated against allow, ask, and deny rules, ensuring no action proceeds without explicit or configured consent from the Dart developer.

The process of documenting a Dart module with Atlas is designed with multiple layers of safety and review. Atlas first drafts a plan in a read-only plan agent, presenting it for developer review before switching to a build agent to execute any changes. This ensures that a Dart developer can understand the proposed documentation strategy before any tools are invoked. For every file edit, including updates to a `README.md` file, Atlas computes a unified diff and surfaces it for approval. This allows the developer to meticulously review exactly what changes Atlas proposes to their Dart project. Furthermore, Atlas snapshots file changes as git patches, so edits can be diffed and rolled back if necessary. This comprehensive review system, combined with permission-gated tool calls, provides a secure and controlled environment for generating and updating documentation for Dart code, preventing unintended modifications and maintaining codebase integrity.

Verifying Dart Code Samples in READMEs with Atlas

Atlas ensures the reliability of every Dart code sample within a generated README by executing it with bash, a critical verification step for documentation in 2026. A code sample that has never been run is considered a liability, so Atlas actively tests each snippet to confirm its accuracy and functionality.

When Atlas writes a README for a Dart module, it includes real code samples and real file paths, such as `example/main.dart`, to illustrate usage. To guarantee these examples are functional and accurate, Atlas employs the bash tool to verify every code sample in the documentation. This means that if a README includes a snippet demonstrating how to use a Dart function, Atlas will attempt to execute that snippet, perhaps by running `dart run example/main.dart` or `dart test` on a specific test case. This rigorous verification process prevents the common problem of outdated or incorrect code examples in documentation, which can mislead developers. By actively running and confirming the behavior of each Dart code sample, Atlas ensures that the documentation truly describes what the code does today, providing a higher level of trust and utility for Dart developers consuming the README.

Step by step

01Run atlas in a package with a pubspec.yaml to initialize Atlas within your Dart project.
02Let Atlas read your libraries, pub dependencies, and analysis options to build a complete context of your Dart codebase.
