Fluro
做为 一个Flutter
的 企业级的路由框架 ,确实不错,能够解决多变的需求状况 ,是时候搞一波了。 我看了官方的demo
,写的有点乱(反正我是这样感受的,老外的代码老是有点抽象),顺便扩展一下传参的问题和使用 Flutter
的 cupertino
转场动画。写了一个demo
, 地址在:在这里在这里,快点我,快快快 git
本文基于 Fluro 目前版本 1.4.0 pub.dev/packages/fl…github
class Application {
static Router router;
}
复制代码
在routes.dart
文件中配置路由,这里须要注意的事首页必定要用“/”配置json
class Routes {
static String root = "/";
static String home = "/home";
static String demoParams = "/deme_params";
static String returnParams = "/return_params";
static String transitionDemo = "/transitionDemo";
static String transitionCustomDemo = "/transitionCustomDemo";
static String transitionCupertinoDemo = "/transitionCupertinoDemo";
static void configureRoutes(Router router) {
router.notFoundHandler = new Handler(
handlerFunc: (BuildContext context, Map<String, List<String>> params) {
print("ROUTE WAS NOT FOUND !!!");
});
/// 第一个参数是路由地址,第二个参数是页面跳转和传参,第三个参数是默认的转场动画,能够看上图
/// 我这边先不设置默认的转场动画,转场动画在下面会讲,能够在另一个地方设置(能够看NavigatorUtil类)
router.define(root, handler: splashHandler);
router.define(home, handler: homeHandler);
router.define(demoParams, handler: demoParamHandler);
router.define(returnParams, handler: returnParamHandler);
router.define(transitionDemo, handler: transitionDemoHandler);
router.define(transitionCustomDemo, handler: transitionDemoHandler);
router.define(transitionCupertinoDemo, handler: transitionDemoHandler);
}
}
复制代码
void main() {
// 注册 fluro routes
Router router = Router();
Routes.configureRoutes(router);
Application.router = router;
runApp(MyApp());
}

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {

首先App启动,先进入 首页Splash 页面,而后 倒计时2秒,再进入home页面markdown

看下图,发现它自带的 转场动画 只有 这几个,没有我喜欢的Flutter
的cupertino
转场动画,侧滑关闭页面,less
继续看源码 ,看下图,最后也是调用了系统的MaterialPageRoute
和 PageRouteBuilder
ide
看下图,本身添加 cupertino
类型 工具
CupertinoPageRoute
