MessageGroup class

A group of consecutive messages from the same sender.

This class implements message grouping logic to create a natural conversation flow by combining messages from the same sender that are sent within a short time period. This follows the Aggregate pattern from Domain-Driven Design.

Messages are grouped when they:

  • Come from the same sender
  • Are sent within the same minute
  • Maintain chronological order

Example usage:

final group = MessageGroup(
  name: "John",
  isSender: false,
  timestamp: "2023-01-01T12:00:00Z",
  messages: [message1, message2],
);
group.sortMessages(); // Ensures proper ordering
