Package Overview

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

The vm_service package provides a Dart library for communicating with the Dart VM service protocol, enabling developers to inspect and control running Dart applications. It supports real-time debugging, performance profiling, and runtime introspection across multiple platforms including Android, iOS, Web, macOS, Windows, and Linux. The package uses WebSocket connections to exchange structured data with the VM, making it essential for tools like debuggers, profilers, and observatories. It is primarily used by development and analysis tools rather than end-user apps.

Use cases

  • Debugging Dart applications
  • Performance profiling
  • Runtime inspection
  • Tooling integration
  • Live app monitoring
  • Development environment diagnostics

Key features

  • WebSocket-based communication
  • Supports all major platforms
  • Integration with Dart DevTools
  • Real-time data streaming
  • Structured JSON-RPC protocol
  • Extensible for custom operations

Suitable for

  • Dart tool developers
  • Debugging frameworks
  • Profiling utilities
  • IDE integrations
  • Development environment builders

Considerations

  • Requires running VM with service protocol enabled
  • Not intended for production app use
  • Needs proper security handling in networked environments
  • Limited to debugging and analysis workflows
  • Depends on SDK internals that may change

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
