1、pubspec.yaml导包,注意格式~
dependencies: flutter: sdk: flutter fluro: ^1.6.3
2、新建路由类,改类是定义页面的路径,然后将页面handler和路径设置到路由中
class routers { static router router; //文件夹须跟main.dart目录同级 static string root = '/'; static string loginpage = '/loginpage'; static string tabspage = '/tabspage'; static string messagedetailpage = '/messagedetailpage'; static string servicesettingpage = '/servicesettingpage'; static void configureroutes(router router) { router.notfoundhandler = handler( handlerfunc: (buildcontext context, map<string, list<string>> params) { print("route was not found !!!"); return null; }); router.define(loginpage, handler: loginhandler); router.define(messagedetailpage, handler: messagedetailhandler); router.define(tabspage, handler: tabshandler); router.define(servicesettingpage, handler: servicesettinghandler); } // 对参数进行encode,解决参数中有特殊字符,影响fluro路由匹配,尤其中文 static future navigateto(buildcontext context, string path, {map<string, dynamic> params, transitiontype transition = transitiontype.infromright, bool replace = false}) { string query = ""; if (params != null) { int index = 0; for (var key in params.keys) { var value = uri.encodecomponent(params[key]); if (index == 0) { query = "?"; } else { query = query + "\&"; } query += "$key=$value"; index++; } } print('我是navigateto传递的参数:$query'); path = path + query; return router.navigateto(context, path, transition: transition, replace: replace); } static void finishalltologinpage() { //跳转指定页面并关闭当前所有页面 //关闭所有页面时会导致tabs_page页面先执行initstate,再执行dispose,导致无法再监听,所以要注意 global.navkey.currentstate.pushandremoveuntil( new materialpageroute(builder: (context) => new loginpage()), (route) => route == null);//会执行所有页面的dispose } }
3、新建router_handler.dart,处理参数和跳转页面
//登录 var loginhandler = new handler( handlerfunc: (buildcontext context, map<string, list<string>> params) { return new loginpage(); }); //消息详情页 var messagedetailhandler = new handler( handlerfunc: (buildcontext context, map<string, dynamic> params) { //取参 string bartitle = params["bar_title"]?.first; string itemdatajson = params["item_data"]?.first; return new messagedetailpage( bartitle: bartitle, itemdatajson: itemdatajson, ); }); //主页tabs var tabshandler = new handler( handlerfunc: (buildcontext context, map<string, list<string>> params) { return new tabspage(); }); //service setting var servicesettinghandler = new handler( handlerfunc: (buildcontext context, map<string, list<string>> params) { return new servicesettingpage(); });
4、调用传参
//对象需要转string string itemdatajson = fluroconvertutils.object2string( _bulletinslist[index]); routers.navigateto(context, routers.messagedetailpage, params: { 'bar_title': "detail", 'item_data': itemdatajson, });
5、接收数据
//string转回对象 bulletins itemdata = bulletins.fromjson(fluroconvertutils.string2map(itemdatajson));
6、问题来了,因为fluro无法直接传中文的,这里就需要用到编码码解码了,也就是encode和decode
class fluroconvertutils { /// fluro 传递中文参数前,先转换,fluro 不支持中文传递 static string flurocnparamsencode(string originalcn) { return jsonencode(utf8encoder().convert(originalcn)); } /// fluro 传递后取出参数,解析 static string flurocnparamsdecode(string encodecn) { var list = list<int>(); ///字符串解码 jsondecode(encodecn).foreach(list.add); string value = utf8decoder().convert(list); return value; } /// string 转为 int static int string2int(string str) { return int.parse(str); } /// string 转为 double static double string2double(string str) { return double.parse(str); } /// string 转为 bool static bool string2bool(string str) { if (str == 'true') { return true; } else { return false; } } /// object 转为 string json static string object2string<t>(t t) { return flurocnparamsencode(jsonencode(t)); } /// string json 转为 map static map<string, dynamic> string2map(string str) { return json.decode(flurocnparamsdecode(str)); } }
完美解决,这也是fluro使用的整个流程,基本小封装了下,还有就是routers需要在main.dart里初始化:
myapp() { // 注册初始化fluro final router = router(); routers.configureroutes(router); routers.router = router; }
