底部面板里选择上传相册图片or拍照上传：

  _showDialog() async {
    if (await G.requestCameraPermission()) {
      showModalBottomSheet(
          context: context,
          builder: (BuildContext context) {
            return Column(
              mainAxisSize: MainAxisSize.min,
              mainAxisAlignment: MainAxisAlignment.center,
              children: <Widget>[
                ARow(
                  height: (G.screenHeight()/667)*40,
                  onPressed: () {
                    print('从相册选择图片');
                    getGallery();//---相册上传事件----
                    Navigator.pop(context);
                  },
                  centerChild: Text(
                    "从相册选择图片",
                    textAlign: TextAlign.center,
                    style: TextStyle(fontSize:(G.screenWidth()/375)*16),
                  ),
                ),
                ARow(
                  height: (G.screenHeight()/667)*40,
                  onPressed: () {
                    print('拍照');
                    getImage();//---拍照上传事件---
                    Navigator.pop(context);
                  },
                  centerChild: Text(
                    "拍照",
                    textAlign: TextAlign.center,
                    style: TextStyle(fontSize: (G.screenWidth()/375)*16),
                  ),
                ),
                SizedBox(
                  height: 10,
                ),
                ARow(
                  height: (G.screenHeight()/667)*40,
                  onPressed: () {
                    Navigator.pop(context);//---取消事件---
                  },
                  centerChild: Text(
                    "取消",
                    textAlign: TextAlign.center,
                    style: TextStyle(fontSize: (G.screenWidth()/375)*16),
                  ),
                ),
              ],
            );
          });
    }
  }

相册上传、拍照上传事件

  Future getImage() async {
    final pickedFile = await picker.getImage(source: ImageSource.camera,maxWidth: 200);
    setState(() {

      _image = pickedFile.path;
    });
  }

  Future getGallery() async {
    final pickedFile = await picker.getImage(source: ImageSource.gallery,maxWidth: 300,maxHeight:400 );
    print(pickedFile.path);
    if (pickedFile.path != null) {

      setState(() {
        _image = pickedFile.path;
      });
    }
  }

查询今日是否打卡

  void  selectToday(){
      HttpRes.singleClockIn({
        "oldGuid":G.user.data.unitGuid,
        "createDate":DateTime.now().toString().substring(0,10),
      }).then((res){
        if (res['code'] == 200) {
          print("查询成功！");
          print(res);
          setState(() {
            if (res['item']!=null){
              mark = 1; //--根据接口查询给mark赋值--
            }else{
              mark = 0;
            }
          });
        }else{
          G.toast(res["msg"]);
        }
      });
  }

调接口获取图片上传路径的方法

  postUploadImg(){
    if(_image==null){
      return G.toast("请先上传图片！");
    }else
 if(textController==null||textController.toString().trim().isEmpty){
      return G.toast("请先输入内容！");
    }else{
      G.loading.show(context);
      HttpRes.postUploadImg(_image).then((res){
        G.loading.hide(context);
        if (res['code'] == 200) {
          picture = res['filePath'];
          this.clockin();//--调用打卡（内容&图片）方法--
        }
      });
    }
  }

传参调接口打卡方法

  void clockin() {
    G.loading.show(context);
    HttpRes.ClockIn({
      //传参数
      //老人ID
      "oldGuid": G.user.data.unitGuid,
      //内容
      "content": textController,
      //图片
      "picture":this.picture ,
      //社区ID
//      "communityGuid": this.arguments['communityGuid'],
    }).then((res){
      G.loading.hide(context);
      // G.loading.hide(context);
      if (res['code'] == 200) {
        G.toalert("打卡成功！");
        G.pushNamed("/clock_history");
        //清空
        setState(() {
          _image=null;
          textController="";
        });
      }else{
        G.toast(res["msg"]);
      }
    });
  }
