Here's the output of fieldtest.dart.js:
var fieldtest;
(function (fieldtest) {
// Class A
var A = (function () {
var _initializer = (function (_this) {
_this.x = 42;
});
function A() {
_initializer(this);
}
return A;
})();
fieldtest.A = A;
// Function foo: (A) → void
function foo(a) {
dart_core.print(a.x);
}
fieldtest.foo = foo;
// Function bar: (dynamic) → void
function bar(a) {
dart_core.print(dart_runtime.dload(a, "x"));
}
fieldtest.bar = bar;
// Function main: () → void
function main() {
var a = new A();
fieldtest.foo(a);
fieldtest.bar(a);
}
fieldtest.main = main;
})(fieldtest || (fieldtest = {}));
