5 | ## Getting Started
6 |
7 | This project is a starting point for a Flutter application.
8 |
9 | A few resources to get you started if this is your first Flutter project:
10 |
11 | - [Lab: Write your first Flutter app](https://flutter.io/docs/get-started/codelab)
12 | - [Cookbook: Useful Flutter samples](https://flutter.io/docs/cookbook)
13 |
14 | For help getting started with Flutter, view our
15 | [online documentation](https://flutter.io/docs), which offers tutorials,
16 | samples, guidance on mobile development, and a full API reference.

3 | You can customize the launch screen with your own desired assets by replacing the image files in this directory.
4 |
5 | You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
