Static Members

Static Members in Dart Overview

Static members belong to the class itself rather than instances of the class. They provide functionality and data that is shared across all instances and can be accessed without creating an object. Dart supports static variables, methods, and initialization logic.

Key Concepts

1. Static Variables

  • Class-level state
  • Shared across all instances
  • Memory efficiency
  • Common use cases

2. Static Methods

  • Utility functions
  • Factory constructors
  • No instance access
  • Pure functions

3. Static Initialization

  • Lazy initialization
  • Complex setup logic
  • Run-once guarantees
  • Error handling

4. Accessing Static Members

  • Class name syntax
  • Inheritance behavior
  • Visibility rules
  • Best practices
