Fetch data from API

To fetch data from RESTful API, You need to use http package Examine the following example:

Future<List<Job>> fetchJobs() async {
  final respone = await http
      .get(Uri.parse('https://jobs.github.com/positions.json?description='));
  final parsed = jsonDecode(respone.body).cast<Map<String, dynamic>>();
  return parsed.map<Job>((json) => Job.fromJson(json)).toList();
}

Search for specific data

Examine the following example:

Future<List<Job>> searchJobs(
    String description, String location, bool fullTime) async {
  String descriptionVariable =
      description.isNotEmpty ? 'description=' + description : 'description=';
  String locationVariable =
      location.isNotEmpty ? '&location=' + location : '&location=';
  String fullTimeVariable = fullTime ? '&full_time=true' : '';

  final response = await http.get(Uri.parse(
      'https://jobs.github.com/positions.json?' +
          descriptionVariable +
          fullTimeVariable +
          locationVariable));
  final parsed = jsonDecode(response.body).cast<Map<String, dynamic>>();
  return parsed.map<Job>((json) => Job.fromJson(json)).toList();
}

For more information, see Fetch data from the internet at Flutter documentation.

Store data on local device

To store data on local device, You can use SQLite database to save your data on your phone. To download the package, go to sqflite

static Future<Database> futureDatabase;
static Database database;

  void onDatabaseIntialize() async {
    var databasePath = await getDatabasesPath();
    String path = join(databasePath, 'saved_jobs_database.db');

    futureDatabase = openDatabase(path, onCreate: (db, version) {
      return db.execute(
          'CREATE TABLE savedJobs(jobID TEXT PRIMARY KEY, type TEXT, jobURL TEXT, createTime TEXT, companyName TEXT, companyURL TEXT, location TEXT, title TEXT, description TEXT, companyLogoURL TEXT, howToApply TEXT)');
    }, version: 1);

    database = await futureDatabase;
  }

To add data (in our case jobs):

Future<void> addJob(Job job) async {
    await database.insert('savedJobs', job.toDatabaseMap(),
    conflictAlgorithm: ConflictAlgorithm.replace);
}

To remove data:

Future<void> deleteJob(String id) async {
    await database.delete('savedJobs', where: 'jobID = ?', whereArgs: [id]);
}
