Hey heyy! During these articles, I’m going to show you how to use ‘fl_chart’ to create different types of charts. Each article will focus on one type of chart. I’ll start simple with things like line charts and pie charts, and then I’ll get more advanced, exploring all the cool stuff you can do with the charts.
Why Use fl_chart?
‘fl_chart’ is like a magic wand for making chart in Flutter. It’s super easy to use, even if I’m just starting out. Plus, it lets me make all kinds of charts that look awesome and showcase my data in an exciting manner.
Line Charts
Line charts in Flutter with ‘fl_chart’ are like a visual journey through your data story. They connect dots to show how things change or grow. Imagine them as your data’s adventure, perfect for showcasing trends or ups and downs. And the best part? You can make these charts look awesome and match your app’s vibe!
Step 1: Add the dependencies to pubspec.yaml file
fl_chart: ^0.65.0
Step 2: Create HomePage
In the ‘home_page.dart’ file, let’s craft three buttons to explore our examples. In the ‘routes.dart’ file I’ve set up navigation to our examples, you can check out the source code for details.
Step 3: Import the package and start to code
import 'package:fl_chart/fl_chart.dart';
Afterward, we’ll create our first example, following a similar code structure with a clear separation between ‘view’ and ‘widget’. We’re starting with ‘view’ part.
Create ‘first_line_chart.dart’ file inside the ‘views’ in ‘lib’ folder.
Next in line, let’s explore our second example together!
Create ‘second_line_chart.dart’ file inside the ‘views’ in ‘lib’ folder.
We’re almost there, and for the grand finale, the last example gets a bit fancy with animations!
Create ‘third_line_chart.dart’ file inside the ‘views’ in ‘lib’ folder.
Thanks for joining me on this fl_chart journey in Flutter! We’ve covered simple to more exciting chart examples. With fl_chart, your app’s data can shine brightly. Have fun, play around, and make those charts yours! Keep exploring the charting magic in Flutter. Happy coding until next time!
