原因：platform没有初始化
解决办法，在FlutterBoost初始化的时候，初始化platform

 Platform platform = new FlutterBoost
                .ConfigBuilder(this, router)
                .isDebug(true)
                .whenEngineStart(FlutterBoost.ConfigBuilder.ANY_ACTIVITY_CREATED)
                .renderMode(FlutterView.RenderMode.texture)
                .lifecycleListener(boostLifecycleListener)
                .build();
        FlutterBoost.instance().init(platform);

2.FlutterBoost的路由初始化失败

解决办法

把参数类型去掉就可以了。。。
FlutterBoost.singleton.registerPageBuilders(<String, PageBuilder>{
      'first': (pageName, params, _) => FirstRouteWidget(),
    });
