Dart null aware operators

int minVal = (a < b) ? a : b;	// if(a < b) {minVal = a;} else {minVal = b;}

var x = y ?? z;  				// assign y to x if y is not null, else z
var x ??= y;    				// assign y to x only if x is null
myObject?.myProp				// (myObject != null) ? myObject.myProp : null
myObject?.myProp?.someMethod()  // chainable
