type 'Null' is not a subtype of type 'Function'

var callee = eval(expression.callee, context);

add a null check here.

if value of callee evaluates to null then it throws an exception stating type 'Null' is not a subtype of type 'Function'

as of now i've handled it in our project by explicitly checking callee value in this way

final callee = eval(expression.callee, context);
    if (callee == null) {
      return;
    }
    return evalCallExpression(expression, context);
