If you are coming from JavaScript you may be used to printing multiple objects to the console with console.log():
console.log('a', 1, 'b', 2); // a 1 b 2
In Dart we can only print Object? to the console with print():
print(1); // 1
print(null); // null
print({'a': 1, 'b': 2}); // {a: 1, b: 1}
But it is totally possible to print multiple objects too, we need to use Records:
final number = 1;
final str = 'Hello World';
print((number, str));
print((DateTime.now(), str));
print((DateTime.now(), count: number, description: str));
print((DateTime.now(), StackTrace.current));
Print the following:
(1, Hello World)
(2024-03-06 15:48:26.514, Hello World)
(2024-03-06 15:48:26.514, count: 1, description: Hello World)
