ChannelState class

State for a payment channel aggregate

Represents the current state of a payment channel at a specific point in time. This state is rebuilt from events during aggregate recovery.

NOTE: Fields are mutable to allow direct state updates in eventHandler. This follows the Eventador AggregateRoot pattern with imperative state management.

Methods

copyWith({int? version, DateTime? lastModified}) → State

Create a copy of this state with updated version and timestamp Subclasses should override to provide type-safe copying

getValidationErrors() → List<String>

Get validation errors Override in subclasses to provide specific error messages

inherited

isNewerThan(State other) → bool

Check if this state is newer than another state

inherited

isSameVersion(State other) → bool

Check if this state is the same version as another state

inherited

isValid() → bool

Validate the state Override in subclasses for custom validation

inherited

nextVersion([DateTime? timestamp]) → State

Create a new version of this state with incremented version

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toMap() → Map<String, dynamic>

Convert state to a map for serialization Override in subclasses to include state-specific data

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
