ListPropertyStream<T extends Object?> class

A property stream for JSON array values.

Provides:

  • A future that completes with the full parsed list
  • An onElement callback for reacting to elements as they start parsing
  • Chainable property getters to access list elements

The onElement callback enables "arm the trap" behavior, firing immediately when a new array element is discovered (before it's fully parsed):

final items = parser.getListProperty('items');
items.onElement((element, index) {
  print('Element $index started');
  // Set up subscriptions for this element
});
