Variable Assignment

We can do variable assignment in Flows.

Flow f = new Flow()
    .inputAs('a', 'b').returnInteger()
    .var('num = 0');

Here we created a local variable num with the value of 0.

Flows have global variables and local variables. Any variable that is passed from outside is a global one. Any variable that is created inside the Flow is a local one. Variables cannot share the same names, so there is no variable overridden in Flow.apex.
