如何在聚合物应用程序中实现主要功能 [英] how to implement a main function in polymer apps
问题描述
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。
不执行代码。
不允许包含带有main函数的第二个dart脚本 -
我的错误在哪里？
Tnx Mica。

Polymer 0.17.0 （Polymer.js 1.0）
main（）async {
await initPolymer（）;
//这里的任何其他代码。
}
Before Polymer 0.17.0
Polymer 0.16.1 介绍了一种更简单的初始化方法。
而不是 main（）使用注释为的方法@whenPolymerReady
//> = Polymer 0.16.1
import'package：polymer /聚合物
export'package：polymer / init.dart';
@whenPolymerReady
void onReady（）{
///这里是自定义安装代码。
}
Before Polymer.dart 0.16.1 p>
//> = Polymer 0.16.0
importpackage：polymer / polymer.dart;
main（）{
initPolymer（）。then（（zone）=> zone.run（（）{
//这里的代码大部分时间$ b Polymer.onReady.then（（_）{
//一些事情必须等待直到onReady回调被调用
//示例看下面链接的讨论
}）;
}））;
}
有关更多详细信息，请参阅Polymer 0.16.0的更改日志b https://pub.dartlang.org/packages/polymer
Before Polymer 0.16.0
//<聚合物0.16.0
importpackage：polymer / polymer.dart;
main（）{
initPolymer（）。run（（）{
//这里的代码大部分时间都在工作
Polymer.onReady.then ）{
//一些东西必须等到onReady回调被调用
//为例子看下面的讨论
}};
}）;
}

I want to implement a main function in an app using polymer.
I tried to implement the main function in the dart file, where the polymer code is implemented. The code is not executed.
Including a second dart script with the main function is not allowed-
Where is my mistake? Tnx Mica.

index.dart
Polymer 0.17.0 (Polymer.js 1.0)
main() async {
await initPolymer();
// Any other code here.
}
Before Polymer 0.17.0
Polymer 0.16.1 introduces a simpler way of initialization.
Instead of main() use a method annotated with @whenPolymerReady
// >= Polymer 0.16.1
import 'package:polymer/polymer.dart';
export 'package:polymer/init.dart';
@whenPolymerReady
void onReady() {
/// Custom setup code here.
}
Before Polymer.dart 0.16.1
// >= 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
});
}));
}
For more details look at the changelog of Polymer 0.16.0 at https://pub.dartlang.org/packages/polymer
Before Polymer 0.16.0
// < 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
});
});
}
