dart - No data from sever API's is not showing on Listview using flutter

Question

I'm fetching data from server APIs, The data is being successfully fetched from the server but the issue is that when the data is provided to Listview it cant be shown. How can I show the data on Listview in a flutter/dart?

Following is the code for fetching data from server API's

  List<String> jobTitles = [];
  List officeNames = [ ];
  List officeLocations = [ ];
  List jobTypes = [ ];

  Future getJobsData() async {
    var response = await http
        .get(Uri.https('hospitality92.com', 'api/jobsbycategory/All'));
    Map<String, dynamic> map = json.decode(response.body);
    List<dynamic> jobData = map["jobs"];

    if (jobTitles.length != 0) {
      officeNames.clear();
      jobTitles.clear();
      officeLocations.clear();
      jobTypes.clear();
    }
    for (var i = 0; i < jobData.length; i++) {
      jobTitles.add(jobData[i]["title"]);
      officeNames.add(jobData[i]["company_name"]);
      officeLocations.add(jobData[i]["company_name"]);
      jobTypes.add(jobData[i]["type"]);
    }

    /* print(jobTitles);
    print(officeNames);
    print(officeLocations);
    print(jobTypes);*/
  }

Here is the design code that I wanted to show:

  Widget listCard(jobTitle, officeName, location, jobType, onPress) {
    return Container(
      child: InkWell(
        onTap: onPress,
        child: Column(
          children: [
            Padding(
              padding: const EdgeInsets.all(8.0),
              child: Card(
                child: Container(
                  decoration: BoxDecoration(
                      gradient: LinearGradient(
                          colors: [Color(0xC000000), Color(0xC000000)])),
                  child: ListTile(
                    leading: CircleAvatar(
                      radius: 30,
                      child: Image.asset(
                        "assets/ic_login.png",
                        height: 28,
                        width: 28,
                      ),
                    ),
                    title: Text(
                      jobTitle,
                      style: TextStyle(
                          fontSize: 16,
                          color: Colors.lightBlue,
                          fontFamily: 'Montserrat',
                          fontWeight: FontWeight.w500),
                    ),
                    subtitle: Row(
                      mainAxisAlignment: MainAxisAlignment.spaceAround,
                      children: [
                        Row(
                          children: [
                            Icon(
                              Icons.home_outlined,
                              color: Colors.black,
                              size: 16,
                            ),
                            Text(

                            ),
                          ],
                        ),

                        SizedBox(

                        Row(

                            Icon(
                              Icons.location_pin,
                              color: Colors.blueGrey,
                              size: 16,
                            ),
                            SizedBox(

                            Text(

                              style: TextStyle(fontSize: 10),
                            ),
                          ],
                        ),
                        SizedBox(
                          width: 10,
                        ),

                        Row(
                          children: [
                            Container(
                              margin: const EdgeInsets.fromLTRB(0, 4, 0, 0),
                              decoration: BoxDecoration(
                                  gradient: LinearGradient(colors: [
                                Colors.lightBlueAccent,
                                Colors.lightBlueAccent
                              ])),
                              child: Padding(
                                padding: const EdgeInsets.all(4.0),
                                child: Text(
                                  jobType,
                                  style: TextStyle(
                                      fontSize: 10,
                                      fontWeight: FontWeight.bold,
                                      color: Colors.white),
                                ),
                              ),
                            ),
                          ],
                        )

                        //ElevatedButton(onPressed: () { }, child: Text("Full Time", style: TextStyle(fontSize: 10),),),
                      ],
                    ),
                  ),
                ),
              ),
            ),
          ],
        ),
      ),
    );
  }

Here is the listview code

ListView.builder(
                    physics: NeverScrollableScrollPhysics(),
                    shrinkWrap: true,
                    itemCount: jobTitle.length,
                    itemBuilder: (context, index) {
                      return listCard(jobTitles[index], officeNames[index],
                          officeLocations[index], jobTypes[index], () {});
                    }),

If I provide the static data to list it will show on listview, but dynamic data is not being shown.

Try To below Code Your problem has been solved:

Create API Call Function :

  Future<List<dynamic>> getJobsData() async {
    String url = 'https://hospitality92.com/api/jobsbycategory/All';
    var response = await http.get(Uri.parse(url), headers: {
      'Content-Type': 'application/json',
      'Accept': 'application/json',
    });
    return json.decode(response.body)['jobs'];
  }

Write/Create your Widget :

Center( 
    child: FutureBuilder<List<dynamic>>(
        future: getJobsData(),
        builder: (context, snapshot) {
          if (snapshot.hasData) {
            return Padding(
              padding: const EdgeInsets.all(8.0),
              child: ListView.builder(
                itemCount: snapshot.data.length,
                itemBuilder: (context, index) {
                  var title = snapshot.data[index]['title'];
                  var company = snapshot.data[index]['company_name'];
                  var skills = snapshot.data[index]['skills'];
                  var description = snapshot.data[index]['description'];
                  var positions = snapshot.data[index]['positions'];
                  return Card(
                    shape: RoundedRectangleBorder(
                      side: BorderSide(
                        color: Colors.green.shade300,
                      ),
                      borderRadius: BorderRadius.circular(15.0),
                    ),
                    child: ListTile(
                      leading: Text(skills),
                      title: Text(title),
                      subtitle: Text(
                        company + '
' + description,
                      ),
                      trailing: Text(positions),
                    ),
                  );
                },
              ),
            );
          }
          return CircularProgressIndicator();
        },
      ),
    ),
