operator []= method

void operator []=(int index, dynamic value)

Sets the model object at the specified index.

Provides convenient indexed assignment to list elements. The list must not be null (asserted at runtime).

Parameters:

• index: The zero-based index where the element should be set.
• value: The new model object of type T to assign at the index.

Throws: An Exception if:

• rawValue is null (list not initialized)
• The index is out of range (negative or >= list length)

Example:

final field = JsonList<UserModel>('users');
field.value = [user1, user2];
field[0] = newUser; // Replace first element

Implementation

operator []=(int index, value) {
  assert(rawValue != null);
  if (rawValue == null) {
    throw Exception("Index $index is out of range");
  }
  if (index < 0 || index >= rawValue!.length) {
    throw Exception("Index $index is out of range");
  }
  rawValue![index] = value;
}
