You could move the above checks to the AppModule class' constructor, and pass in
app as a final field to this class.

+    var window = JS('', '#.window', app);
+    if (app == null) {
+      throw new UnsupportedError('Not supported by current browser');
+    }

You might want to check this in the constructor of this class.

+    JS('void', '#.create(#)', window, url);
+  }
+}
+
+final app = new AppModule._();
