I have list of categories and tapping on each of them shows users of that category in new screen. The new screen has an image widget and text widget. I am getting this error if a user has a profile picture, and if there's no profile picture associated with that user, a default picture is shown which doesn't throw this error.

Widget _getProfilePic(Pro pro) {



    // If the pro has provided a profile picture

    if(pro.profilePhoto.length > 0) {



      // If the pro is available for a video call

      if(statusMap[pro.onlineStatus] == "Online, available") {

        return CircleAvatar(

            radius: 30.0,

            backgroundImage: pro.profilePhoto.startsWith("./profilepics") ? NetworkImage("" + pro.profilePhoto.substring(2)) : pro.profilePhoto);

      }

      // If pro is not available

      else {

        return CircleAvatar(

            radius: 30.0,

            backgroundImage: pro.profilePhoto.startsWith("./profilepics") ? NetworkImage("" + pro.profilePhoto.substring(2)) : pro.profilePhoto);

      }



    }

    // Else, provide a default icon

    else {

      // If the pro is available for a video call

      if(statusMap[pro.onlineStatus] == "Online, available") {

        var profileImg = Image.asset('icons/default_profile_icon.png', height: 60.0);



        return Image.asset('icons/default_profile_icon.png', height: 60.0);



      }

      // If the pro is not available

      else {

        return Image.asset('icons/default_profile_icon.png', height: 60.0);

      }

    }

This is the Pro class model:

class Pro extends User {

  String company;

  String experience;

  double rating;

  int reviewCount;

  int onlineStatus;

  String proId;



  Pro();



  // Returns a Pro created from JSON

  factory Pro.fromJson(Map<String, dynamic> json) {

    Pro pro = Pro();



    pro.proId = json['ProID'] as String;

    pro.fullname = json['FullName'] as String;

    pro.company = json['Company'] as String;

    pro.experience = json['about'] as String;

    pro.rating = json['ReviewAvg'] != null? double.tryParse(json['ReviewAvg']) : 0.0;

    pro.reviewCount = json['ReviewCount'];

    pro.onlineStatus = json['OnlineStatus'];

    pro.profilePhoto = json['profile_pic'] as String;



    return pro;

  }



}



// Converts a http response body into a List<Pro>

  List<Pro> parsePros(String responseBody) {

    final parsed = json.decode(responseBody).cast<Map<String, dynamic>>();

    return parsed.map<Pro>((json) => Pro.fromJson(json)).toList();

  }

You probably need to wrap pro.profileImage in NetworkImage in the two places you test for ./profilepics
