mic*_*ica 10 dart dart-polymer
我想在使用聚合物的应用程序中实现主要功能.
我试图在dart文件中实现main函数,其中实现了聚合物代码.代码未执行.
不允许包含带有主要功能的第二个飞镖脚本 -
我的错误在哪里？Tnx Mica.

聚合物0.17.0(Polymer.js 1.0)
main() async {
await initPolymer();
// Any other code here.
}
在Polymer 0.17.0之前
Polymer 0.16.1引入了一种更简单的初始化方法.而不是main()使用带注释的方法@whenPolymerReady
// >= Polymer 0.16.1
import 'package:polymer/polymer.dart';
export 'package:polymer/init.dart';
@whenPolymerReady
void onReady() {
/// Custom setup code here.
}
在Polymer.dart 0.16.1之前
// >= Polymer 0.16.0
import "package:polymer/polymer.dart";
main() {
initPolymer().then((zone) => zone.run(() {
// code here works most of the time
Polymer.onReady.then((_) {
// some things must wait until onReady callback is called
// for an example look at the discussion linked below
});
}));
}
有关详细信息,请参阅https://pub.dartlang.org/packages/polymer上的Polymer 0.16.0的更改日志
在Polymer 0.16.0之前
// < Polymer 0.16.0
import "package:polymer/polymer.dart";
main() {
initPolymer().run(() {
// code here works most of the time
Polymer.onReady.then((_) {
// some things must wait until onReady callback is called
// for an example look at the discussion linked below
});
});
}
