With nullsafety, by default dart interpret that all variables should be not null, so, you always need to set the initial value. However, if you want a nullable variable, you need to tell dart using ? like (int? varName) that this specific variable is nullable. Now, LATE is a way to tell dart that this variable is not nullable, but the initial value will be set in another point of the code before you using it. In other words, this is a compromise that you will set the initial value before using it.
