[Flutter] Workmanager inputData is null when trying to retrieve in background task Flutter

I'm having trouble passing and retrieving inputData in Flutter's Workmanager. I'm trying to send some data (like id and date) when registering a task, but when I try to access the inputData in the background task, I keep getting null.

Workmanager().registerOneOffTask(
"simpleTask", // Unique task name
"simpleTask", // The task name
tag: '1',
inputData: {'id': '1', 'date': '16-10-2024'}, // Input data to be passed
);

void callbackDispatcher() {
Workmanager().executeTask((task, inputData) {
print('Task name: $task');
print('Input data: $inputData'); // This prints null
print('Notification id: ${inputData?["id"]}');
print('Notification date: ${inputData?["date"]}');
return Future.value(true);
});
}

Workmanager().initialize(
callbackDispatcher,
isInDebugMode: true // For debugging
);
