flutter future builder

 FutureBuilder<String>(
        future: _fetchNetworkCall, // async work

      Container(

Example of future function:Future getProjectDetails() async {  List<ProjectModel> projetcList = await someFutureCall();  return projetcList;    }

class ProjectModel {  String id;  String createdOn;  String lastModifiedOn;  String title;  String description;  ProjectModel({    this.id,    this.createdOn,    this.lastModifiedOn,    this.title,    this.description,  });}
