Firebase 分页可编辑&；火基

我浏览过互联网，没有发现任何东西，我肯定不是唯一一个想和Firebase合作的人

我要创建一个非常简单的表：

带有列表的页面

class CentreViewEnquiriesList extends StatefulWidget {
  final CentreData centreData;
  CentreViewEnquiriesList({this.centreData});
  @override
  _CentreViewEnquiriesList createState() => _CentreViewEnquiriesList();
}

class _CentreViewEnquiriesList extends State<CentreViewEnquiriesList> {
  int _rowsPerPage = PaginatedDataTable.defaultRowsPerPage;
  @override
  Widget build(BuildContext context) {
    return SingleChildScrollView(
      child: Container(
        padding: EdgeInsets.all(20),
          child: PaginatedDataTable(
              header: Text('Enquiries'),
              columns: [
                DataColumn(label: Text('Enquiry Date')),
                DataColumn(label: Text('Enquiry Person')),
                DataColumn(label: Text('Enquiry Status')),
              ],
              source: EnquiryDataSource(widget.centreData),
              onRowsPerPageChanged: (r) {
                setState(() {
                  _rowsPerPage = r;
                });
              },
              rowsPerPage: _rowsPerPage,
          ),
      ),
    );
  }
}

通常我会使用类似于StreamBuilder的东西，但是因为它需要类有一个状态，所以它不会工作

以下是我获取数据的方法：

//List of Enquiries to show on CentreView Enquiries DataTable
  List<EnquiryData> _enquiryListFromSnapshot(QuerySnapshot snapshot){
    return snapshot.documents.map((doc) {
      return EnquiryData(
      enquiryID: doc.data['enquiryID'],
      parentFirstName: doc.data['firstName'],
      parentLastName: doc.data['lastName'],
      enquiryStatus: doc.data['enquiryStatus'],
      );
    });
  }

  //get stream of all enquiries
  Stream<List<EnquiryData>> get enquiries {
    return centresCollection.document(centreID).collection('enquiries').snapshots().map(_enquiryListFromSnapshot);
  }

//要在CentreView查询数据表上显示的查询列表
列表_inquiryListFromSnapshot（QuerySnapshot快照）{
返回snapshot.documents.map（（doc）{
返回查询数据(
查询ID:doc.data['inquiryID']，
parentFirstName:doc.data['firstName']，
parentLastName:doc.data['lastName']，
查询状态：文档数据['inquiryStatus']，
);
});
}
//获取所有查询的信息流
欢迎查询{
返回centresCollection.document（centreID）.collection（'inquiries'）.snapshots（）.map（_inquiryListFromSnapshot）；
}

//List of Enquiries to show on CentreView Enquiries DataTable
  List<EnquiryData> _enquiryListFromSnapshot(QuerySnapshot snapshot){
    return snapshot.documents.map((doc) {
      return EnquiryData(
      enquiryID: doc.data['enquiryID'],
      parentFirstName: doc.data['firstName'],
      parentLastName: doc.data['lastName'],
      enquiryStatus: doc.data['enquiryStatus'],
      );
    });
  }

  //get stream of all enquiries
  Stream<List<EnquiryData>> get enquiries {
    return centresCollection.document(centreID).collection('enquiries').snapshots().map(_enquiryListFromSnapshot);
  }
