商品詳情頁布局

商品詳情頁一般都是這個商城app中布局最多的一個界面慷暂，也是各種交互比較多的界面，整整寫了一天才寫完(其實(shí)還沒完帕涌，后面有些無關(guān)緊要的圖片就沒有寫了)
還是一點(diǎn)來吧

首先是路由配置和數(shù)據(jù)獲取

路由配置:

Handler detailsHandler = Handler(
   handlerFunc: (BuildContext context,Map<String,List<String>> params){
      String itemCode = params["itemCode"].first;//傳遞請求參數(shù)
      print("傳遞的itemCode是: ${itemCode}");
      return DetailsPage(itemCode);
   }

 static String detailsPage = "/detailsPage";
 router.define(detailsPage,handler: detailsHandler);

//使用:
onTap: (){
          Application.router.navigateTo(context, "/detailsPage?itemCode=${sectionListItem.productCode}");
       },

數(shù)據(jù)獲取:

                                  SizedBox(height: 8.0,),
                                  DetailsDescribe(),

                                  DetailsDelivery(),
                                  SizedBox(height: 8.0,),
                                  DetailsEvaluate(),
                                  SizedBox(height: 8.0,),
                                  DetailsCompany(),
                                  SizedBox(height: 8.0,),
                                  DetailsImgText(),
                                  SizedBox(height: 80.0,)
                               ],
                            ),
                          ),
                          Positioned(
                             bottom: 0,
                             left: 0,
                             child: DetailsBottom(),
                          )
  
                       ],
                  );
                   
                }else{
                    return Center(
                      child: Text("暫無數(shù)據(jù)"),
                    ); 
                }
          }
      )
    );
  }

  Future _getDetailPage(BuildContext context) async{
      await Provide.value<DetailsPageProvide>(context).getDetailsPageData(itemCode);
      return "加載完成";
  }

}

從ListView中就是我拆分的詳情頁部分的各個組件迅涮。下面還是將各個組件中的代碼貼出來。

頂部圖片輪播
import 'package:flutter/material.dart';
import 'package:provide/provide.dart';
import '../../provide/details_provide.dart';
import 'package:flutter_swiper/flutter_swiper.dart';



class TopSwiper extends StatelessWidget {
  

  @override
  Widget build(BuildContext context) {
    return Provide<DetailsPageProvide>(
         builder: (context,child,val){
            var coverImages = val.datas.coverImages;
            return Container(
                  color: Colors.white,
                  height: MediaQuery.of(context).size.height*0.6,
                  child: Swiper(
                    itemBuilder: (BuildContext context,int index){
                        return Image.network("${coverImages[index]}");
                    },
                    onTap: (index){
                        print("點(diǎn)擊了輪播組件:${index}");
                    },
                    itemCount: coverImages.length,
                    pagination: buildSwiperPagintion(),
                    autoplay: true,
                    
                  ),
                );
         },
    );
  }

  buildSwiperPagintion(){
     return SwiperPagination(
        builder: FractionPaginationBuilder(
           color: Colors.white,
           activeColor: Colors.orange
        )
     );
  }
}

這個輪播插件還是挺好用的虎眨，就是這個Page指示器和app上的不一樣，由于這個插件只提供了兩種樣式，如果想要和app中的一樣需要自定義這個SwiperPagination, 后面完成后嗽桩，來試試自己自定義這個東東岳守。

這里面代碼就比較多了譬重，主要是我將這個選擇商品規(guī)格和數(shù)量的底部sheet和這個省市區(qū)選擇放在了一起了。 這里面注意這個底部彈出框是用這個: showModalBottomSheet,非常好用罐氨，不像以前原生要做個底部自定義彈窗(唉)臀规。 還有就是我的省市區(qū)選擇是用的國人寫的插件city_pickers,挺好的，簡單方便栅隐。

給圖片選擇一個填充方式: fit:BoxFit.fitWidth.

這個主要就是在嵌入商品詳情頁的時候邑遏，是要懸浮在詳情頁其它組件之上且在底部:

 Positioned(
                             bottom: 0,
                             left: 0,
                             child: DetailsBottom(),
                          )
商品詳情頁就這么多東西，然后其中的各種數(shù)據(jù)交互的邏輯都還沒做恰矩，這個得和后面的購物車結(jié)合起來做。最后這個項(xiàng)目完成后代碼會上傳到gitHub上憎蛤。 其次其中寫得不好的請指正外傅，共同進(jìn)步。
