How to create a custom sign-in screen for your FlutterFlow app?

Before you begin: Getting Started with FlutterFlow

FlutterFlow is a no-code development platform that allows you to create any app you can imagine without writing a single line of code.
To start creating a custom sign-in screen, you need to have an account with FlutterFlow. Go to FlutterFlow and sign up.

Step 1: Create a new project

After you've logged in to FlutterFlow, the first step is to create a new project. Click on the New Project button located on the top right corner of the dashboard.

A dialog box will appear, prompting you to enter the name of your new project. Once you’ve entered the appropriate name for your project, proceed by clicking the Create button.

Step 2: Navigate to Pages

Next, on the left side of your workspace, you should see the Pages tab; click on it. This will open the Pages section where you can see all the pages of your app.

Step 3: Add new page

Click the + button to add a new page. In the dialog box, enter the name for your new page (like Sign-in or Login ) and then press Enter.

Step 4: Design Your Sign-in Screen

You will be directed to the newly created page, where you will design the custom sign-in screen. In the screen design window, you can drag and drop elements (like Textboxes for username and password fields, Image for app logo, Buttons for sign-in, etc.) from the elements panel on the right side onto your screen canvas.

• Adding App Logo: Drag and drop an Image element from the panel onto the screen canvas. In the Image Element's properties, you can upload an image file to be used as the App's Logo.

• Adding Input Fields: Just under the logo, drag and drop two TextFields elements from the right panel for the Username/Email and Password fields. In the TextField's properties, you can customize the placeholder content to match Username/Email and Password respectively. Also, ensure to make the Text Obscure feature true in the Password field to hide entered passwords.

• Adding a Sign-in button: From the panel, select the button widget and drop it just below the password field. Change its label to something like "Sign in" or "Log in".

• Adding Text for Sign-up: If you're also offering a sign-up feature, drag and drop a Text widget below the sign-in button and type in "Don't have an account? Sign up." You can make "Sign up" tappable by wrapping it with GestureDetector or InkWell.

• Incorporate nice UI: Customize colors, fonts, sizes, padding and margin on the right property inspector for your widgets.

Step 5: Setup Sign-in Functionality

• In FlutterFlow's Firebase tab, you need to setup Firebase authentication. Click Firebase tab on the left hand side menu, select Email/Password, enable it and save.

• Back on the design canvas, select the sign-in button, and in the Click Event dropdown on the right side, select Login in Firebase section.

• Make sure to provide the keys as the corresponding form fields (Username/Email key to email TextField and Password Key to password TextField).

Step 6: Preview your Custom Sign-in Screen

Finally, let's preview how our custom sign-in screen will appear to users. Click on the Preview tab at the top right corner of your workspace.

If everything looks as you desired, great job! You’ve successfully created a custom sign-in screen. Be sure to regularly save your work by clicking on the Save button at the top-right corner.

Note: You need to have Firebase set up in your project (Sign into Firebase with your Google account and create a new project) to be able to preview your work at FlutterFlow.
