3 | A new Flutter project.
4 |
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://docs.flutter.dev/get-started/codelab)
12 | - [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
13 |
14 | For help getting started with Flutter development, view the
15 | [online documentation](https://docs.flutter.dev/), which offers tutorials,
16 | samples, guidance on mobile development, and a full API reference.

/example/analysis_options.yaml:
--------------------------------------------------------------------------------
1 | # This file configures the analyzer, which statically analyzes Dart code to
2 | # check for errors, warnings, and lints.
3 | #
4 | # The issues identified by the analyzer are surfaced in the UI of Dart-enabled
5 | # IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be
6 | # invoked from the command line by running `flutter analyze`.
7 |
8 | # The following line activates a set of recommended lints for Flutter apps,
9 | # packages, and plugins designed to encourage good coding practices.
10 | include: package:flutter_lints/flutter.yaml
11 |
12 | linter:
13 | # The lint rules applied to this project can be customized in the
14 | # section below to disable rules from the `package:flutter_lints/flutter.yaml`
15 | # included above or to enable additional rules. A list of all available lints
16 | # and their documentation is published at https://dart.dev/lints.
17 | #
18 | # Instead of disabling a lint rule for the entire project in the
19 | # section below, it can also be suppressed for a single line of code
20 | # or a specific dart file by using the `// ignore: name_of_lint` and
21 | # `// ignore_for_file: name_of_lint` syntax on the line or in the file
22 | # producing the lint.
23 | rules:
24 | # avoid_print: false # Uncomment to disable the `avoid_print` rule
25 | # prefer_single_quotes: true # Uncomment to enable the `prefer_single_quotes` rule
26 |

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.
