Customizing Your Flutter SearchDelegate Background and AppBar Color

Are you working on a Flutter project where you want to maintain your app's aesthetic when users tap on the search function? If your setup has a black AppBar and background, but they revert to white when the search icon is clicked, you'll want to customize the SearchDelegate colors. Here’s how to ensure your search page matches the rest of your application's style.

The Problem

When users initiate a search by clicking the search icon, the SearchDelegate displays a default white background and AppBar, disrupting the cohesive look of your app. Your goal is to maintain a dark theme throughout the app—even on the search page.

The Solution

To achieve a unified appearance while using SearchDelegate, you will need to override several methods provided by SearchDelegate. Let’s break this down into manageable sections.

1. Overriding the AppBar Theme

To customize the AppBar color within SearchDelegate, override the appBarTheme method. This allows you to set your preferred color and other properties for the AppBar.

Here’s an example:

2. Changing the Background Color of Suggestions

Next, you’ll want to adjust the background color of the suggestions that appear when users begin typing. This can be done by updating the buildSuggestions method.

Example implementation:

3. Customize the Results Background

Similarly, customize the background for the results displayed after the user performs a search by overriding the buildResults method:

Conclusion

By following these steps, you can ensure that the color scheme of your search functionality matches the rest of your app, even when using a SearchDelegate. Not only will this enhance the user experience, but it’ll also reinforce your brand's identity through consistent styling.

Implement these changes to keep your application looking cohesive and polished. Happy coding!
