A Dart utility class that helps track multiple asynchronous operations and wait for all of them to complete. It provides a clean way to manage concurrent tasks, such as API calls or file operations, by maintaining a collection of pending operations and offering methods to check completion status or await their resolution. Ideal for scenarios requiring coordination between async processes, it enhances code readability and reliability when handling complex workflows.
Use cases
- Managing concurrent API requests
- Tracking background task completion
- Coordinating multiple file operations
- Synchronizing async initialization steps
- Handling batch data processing
Key features
- Tracks multiple pending operations
- Waits for all operations to complete
- Provides completion status checks
- Simple and intuitive API
- Supports cancellation
Suitable for
- Apps with multiple async tasks
- Complex initialization flows
- Background processing workflows
- Testing async logic
- State management in Flutter apps
Considerations
- Not suitable for long-running operations without proper error handling
- Requires manual cleanup of operation references
- Limited to synchronous waiting patterns
- Does not handle retries or timeouts
- Best used with proper error propagation
