Saving Data in Flutter

Learn about some of the most common storing options in Flutter: SharedPreferences, Flutter secure Storage, local files, SQL and NoSQL Databases and cloud tools like Firebase.

While most apps need to store data in one way or another, each project has different needs. You should take into account several factors, like data size, security, performance, persistence, target platforms and complexity. Learn how to choose the right solution based on real world scenarios.

In this quick challenge episode, you’ll see three different real world scenarios for potential apps. For each scenario, try to pick the best storage option!

Learn how to leverage SharedPreferences in Flutter, and the target platforms you can address. See the data types you can store, and the methods to read, add, edit, and update your data.

In this episode, you will create a helper class that contains the methods to insert, read, update and delete data to your SharedPreferences instance.

In this episode, you’ll see how to connect your UI to the helper class that interacts with SharedPreferences, and how to dynamically view and change data from your app.

In this challenge, you will add another field to the settings: the option to show the date: once this is done you will update your helper class to read and write the new field to SharedPreferences.

In this episode, you’ll transform your app so that your settings will be stored securely, using the flutter_secure_storage package.

In this episode, you will learn where you can store your files, and how to leverage path and path_provider to set and retrieve paths that deal with files.

In this episode, you will see how to write content for a recipe in a new file, and then retrieve its content.

In this episode, you will create the screen that shows all the files in the documents directory of your app, leveraging a ListView widget and the path_provider package.

In this episode, you will create the screen that shows the details of a single text file and allows reading and writing its content.

Add the function to delete a file, from the file list screen and the file screen, and implement a correct navigation for the app.

One of the most common approaches when storing data is using the JSON format. Learn how to transform your custom objects into JSON, and then from JSON content create instances of your classes.
