How to create a custom theme for your FlutterFlow app?

Step 1: Navigate to Your FlutterFlow Project

FltuterFlow projects lie at the heart of the FlutterFlow's UI builder. To start, go to the FlutterFlow dashboard and open up the project you wish to apply the custom theme to.

Step 2: Open The Theme Editor

On the left side bar, locate and click on the ‘Themes’ icon. This opens up the ‘Theme Editor’ where you can design and apply a customized theme for your app.

Step 3: Select The Base Theme

Before creating a custom theme, you have to decide on the type of theme you want to customize. There are two primary types of themes in FlutterFlow: light theme and dark theme. Depending on your preference, click either of the icons at the top of the Theme Editor. This opens up a detailed view of the chosen theme.

Step 4: Modify the Colors

Every theme has five color properties: primary, secondary, background, surface, and error. To modify these, simply click on the color palette beside each property and set your preferred color. For more precise color setting, you could enter the specific Hex color code.

Step 5: Customize Text Theme

FlutterFlow allows you to customize various text styles within your app. These include headline1, headline2, bodyText1, bodyText2, and more. Under each text style, click on edit style to modify the font size, letter spacing, font weight, font style, and text color.

Step 6: Customize Buttons

To modify button styles, scroll towards the bottom of the Theme Editor. Here, you will discover two button styles: elevated button and outlined button. To modify the button style, click on edit style, which opens a dialog box allowing you to modify the text style, button color, and shape.

Step 7: Save And Apply Theme

After customizing the theme to your satisfaction, it's time to save and apply it. Click on the save button at the top right corner of the Theme Editor. Once saved, the new theme is automatically applied to your FlutterFlow app.

Step 8: Test Your Theme

Finally, test your new theme to verify whether it successfully applied and to see how it manifests within your app. To do this, go back to your main FlutterFlow project page and click on the preview button at the top right. This launches your app in a new window, allowing you to interact with it and see how your new theme looks.

Note: Remember that themes affect the entire app, not just a single screen or widget. Any changes made in the Theme Editor will replicate across all screens of the application. Where necessary, tweak individual widgets to override the theme for that specific widget.
