Nulls

Everything is null in Dart

To check if something is null, we can use something like

if (myVariable != null) {
  // ...
}

If our variable is null, we can assign a default value too

myVariable = myVariable ?? 0;

And we can get the null value avoiding an error using ?

var myVariable = null;
print(myVariable?.toString());
