What are the different types of data that can be stored in a FlutterFlow database?

Step 1: Introduction to FlutterFlow and its Database

Before diving into the different types of data that can be stored in a FlutterFlow database, it is important to understand what FlutterFlow is. FlutterFlow is a low-code, powerful app builder designed for speed and productivity. It utilizes Google's UI toolkit, Flutter, thus allowing developers to rapidly build natively compiled applications for mobile, web, and desktop from a single codebase.

FlutterFlow's backend is powered by Firebase, a popular Backend-as-a-Service platform that offers NoSQL databases, cloud functions, hosting, and more. In this tutorial, we are particularly interested in the types of data that could be stored in FlutterFlow's Firestore database.

Step 2: Understanding Firestore Database Structure

A typical Firestore database comprises collections, documents, and fields. These elements are organized in a hierarchical order: a database is made up of collections, with each collection containing multiple documents, and each document comprising multiple fields.

• Collections are a way of grouping documents together.
• Documents are individual entries or records that contain relevant data.
• Fields within each document store the actual pieces of data.

Step 3: Exploring Data Types in FlutterFlow Database

In Firestore, and thus in the FlutterFlow database, several types of data can be stored. Here are the different types of data:

• String: This is essentially a sequence of characters. Names, titles, and any other text-based content would typically be stored as strings.

• Number: This stores both integers (whole numbers) and floats (numbers with decimal points).

• Boolean: This is a simple true or false value.

• Map: This holds key-value pairs. Each key must be a string type, but the value can be of any data type.

• Array: This is a list of other values. These can be of any type, and not all values in the array need to be of the same type.

• Null: This represents an absence of value.

• Timestamp: This represents a point in time.

• Geopoint: This allows the storage of geographic coordinates (latitude and longitude).

• Reference: This stores a reference to another document in the database.

Step 4: Understanding How to Use These Data Types

Now, let's see a demonstration on how you can use these data types when using FlutterFlow to store data in Firestore:

String, Number, Boolean:

Adding a new field of type String, Number, or Boolean is pretty straightforward. You just need to:

• Click on the document to which you want to add a field.
• Click on Add Field.
• Enter the field name and select the type (String, Number, or Boolean), then enter the value.
• Click Save.

Map:

To add a field of the map data type:

• Follow the same steps as above, but select Map for type.
• Click on Add Field within the map value section to add nested fields. Insert the key and value for each nested field.
• Click Save.

Array:

Adding a field of type Array is similar:

• Follow the steps in adding a field but select Array for the type.
• Click on Add Element within the array value section to add elements. It opens a selection for the type of the element you want to add to the array (e.g., string, number, etc.). Add the value you want for each of these elements.
• Click Save.

Geopoint and Timestamp:

For Geopoint and Timestamp:

• These types are usually autogenerated by Firestore, for example, recording when a document was created or the location a document pertains to.
• However, you can manually add them by creating a new field, selecting the type as Geopoint or Timestamp, and entering the corresponding values.

Reference:

For the Reference data type:

• Add a field, and in the type, select Reference.
• You will need to enter the path to the document you want to reference.

That's all you need to know about the different types of data that can be stored in a FlutterFlow database. Take the time to understand these concepts and experiment with them in your projects.
