Making fromMap Constructors Require Certain Fields

	class SomeClass {
	String id;
	String foo;
	String bar; // required
	String zap; // required

	SomeClass.fromMap(Map<String, dynamic> inputMap) {
	this.id = inputMap['ID'];
	this.foo = inputMap['Foo'];
	this.bar = inputMap['Bar'];

	class SomeClass {
	String foobar;

	void someMethod(String newValue) {
	if (foobar == null) {
	foobar = newValue;
	}
	}

	// OR //
