"<p>This Flutter tutorial shows you how to deal with loading data from cache along with provider. Caching is important when dealing with data that doesn't change often, or when dealing with slow networks. This video will show you how to use Shared preferences plugin to load data from cache.</p> <p>To use the Shared Preferences plugin, you first need to add it to your pubspec.yaml file. Then, you can create a new instance of the SharedPreferences class. Once you have created an instance, you can then use the setString() method to save data to cache as we did in this <a href="https://devbrains.tn/tutorials/how-to-cache-data-in-your-app">tutorial</a>. To retrieve data from cache, you can use the getString() method.</p> <p>Overall, the Shared Preferences plugin is a great way to load data from cache in flutter</p> <pre> <code>void loadTasksFromCache() async{ final prefs = await SharedPreferences.getInstance(); if(prefs.containsKey(globals.todoTasksKey)){ final String? data = prefs.getString(globals.todoTasksKey); List<dynamic> _oldTasks= json.decode(data!); List<Task> _tasksList = List<Task>.from(_oldTasks.map((element)=>Task.fromJson(element))); for(int i=0;i<_tasksList.length;i++){ add(_tasksList[i]); } } }</code></pre>"
