Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

acyclic_steps is a Dart package that provides an explicit, acyclic step dependency framework designed for managing complex workflows with clear dependencies. It enables concurrent evaluation of independent steps while ensuring no circular dependencies exist, promoting predictable execution order. The framework supports dependency injection, making it ideal for testing and modular application design. Built by Google, it integrates seamlessly into Flutter projects across all major platforms.

Use cases

  • Testing complex workflows
  • Managing task dependencies in CI/CD
  • Building modular application pipelines
  • Simulating state transitions
  • Implementing configurable build processes

Key features

  • Acyclic dependency graph enforcement
  • Concurrent step execution
  • Built-in dependency injection
  • Explicit step definitions
  • Support for platform-agnostic workflows

Suitable for

  • Test automation frameworks
  • CI/CD pipeline builders
  • Modular app architectures
  • Complex state machine implementations
  • Developers needing deterministic execution order

Considerations

  • Requires careful step definition to avoid cycles
  • Best suited for structured, sequential workflows
  • May add overhead for simple tasks
  • Limited documentation beyond basic examples
  • Depends on proper dependency management practices

Dart Neats

A collection of a small neat packages for dart.

Disclaimer: This is not an officially supported Google product.

This repository is meant as a playground where small neat packages are cultivated. If package grows too large and complex and needs a dedicated issue tracker it should be moved to a dedicated repository.

Each folder in this repository contains a neat pub package. This project aims to use a separate package whenever it makes sense to have an independent major version. This often means splitting functionality into separate packages, which can be reused independently.

Package Description Version Test
acyclic_steps An explicit acyclic step dependency framework with concurrent evaluation and dependency injection. pub package acyclic_steps
canonical_json Encoder and decoder for a canonical JSON format, useful when cryptographically hashing or signing JSON objects. pub package canonical_json
chunked_stream Utilities for working with chunked streams, such as byte streams which is often given as a stream of byte chunks with type Stream<List<int>>. pub package chunked_stream
dartdoc_test Utilities for testing code snippets embedded in documentation comments. pub package dartdoc_test
http_methods List of all HTTP methods registered with IANA as list of strings, and metadata such as whether a method idempotent. pub package http_methods
neat_cache A neat cache abstraction for wrapping in-memory or redis caches. pub package neat_cache
neat_periodic_task Auxiliary classes for reliably running a periodic task in a long-running process such as web-server. pub package neat_periodic_task
pem PEM encoding/decoding of textual keys following RFC 7468, supporting both lax/strict-mode, and certificates chains of concatenated PEM blocks. pub package pem
retry Utility for wrapping an asynchronous function in automatic retry logic with exponential back-off, useful when making requests over network. pub package retry
safe_url_check Check if an untrusted URL is broken, without allowing connections to a private IP address. pub package safe_url_check
sanitize_html Function for sanitizing HTML to prevent XSS by restrict elements and attributes to a safe subset of allowed values. pub package sanitize_html
slugid A URL-safe base64 encoding for UUIDv4 stripped of padding. Useful when embedding short random UUIDs in URLs. pub package slugid
typed_sql Package for doing SQL with some type safety. pub package typed_sql
vendor Utility for vendoring packages into a project and rewriting import/export statements. pub package vendor

Repository Management

Packages in this repository uses pub workspaces a single dart pub get will resolve dependencies for all of them. Configuration of Github Actions, issue templates, issue labels, etc is automated with scripts in tool/.

Contributing

We love patches and contributions, please refer to CONTRIBUTING.md for technicalities on CLA and community guidelines. As this project aims to build neat packages using other neat packages we might also accept proposals for new neat packages, though it's often easier to publish independently.
