Crafting Search Bars in Flutter – A Step-by-Step Guide
Crafting Search Bars in Flutter
Search bars are an essential element of modern web design and development. They enable users to quickly and easily find the content they’re looking for — whether it’s a product, a service, or just information. With the rise of mobile development, search bars have become a prominent feature on apps as well. In this article, we’ll be taking a look at how to craft search bars in the popular cross-platform framework: Flutter.
What is Flutter?
Flutter is an open-source UI software development kit created by Google. It is used to develop applications for Android, iOS, Windows, Mac, Linux, Google Fuchsia, and the web from a single codebase. The language used to craft Flutter apps is Dart, Google's own language. Flutter is becoming increasingly popular due to its ability to create fast and beautiful user interfaces.
Creating a Search Bar with Flutter
The first step in creating a search bar is setting up the TextField. This is where users will enter their query. To create a basic TextField with Flutter, add the following code:
TextField(
decoration: InputDecoration(
hintText: 'Enter your query'
)
)
Next, create a function to handle the query. This function should take in the user’s query as an argument and then execute a search based on that query.
void doSearch(String query) {
// Execute search with query
}
Finally, link the TextField to the search function. To do this, add an onChanged property to the TextField that calls the search function:
TextField(
onChanged: (String query) {
doSearch(query);
},
decoration: InputDecoration(
hintText: 'Enter your query'
)
)
And that’s it! You’ve now created a basic search bar with Flutter. You can customize it further by adding features such as autocomplete, or changing the look and feel with different styling options. There are many possibilities for creating search bars with Flutter.
Conclusion
As you can see, creating search bars with Flutter is simple and straightforward. With just a few lines of code, you can add a rich, powerful search feature to your app. We hope that this article has given you insight into how to create search bars in Flutter — happy coding!
