A new Flutter project.
## Getting Started
This project is a starting point for a Flutter application.
A few resources to get you started if this is your first Flutter project:
- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
For help getting started with Flutter development, view the
[online documentation](https://docs.flutter.dev/), which offers tutorials,
samples, guidance on mobile development, and a full API reference.

# This file configures the analyzer, which statically analyzes Dart code to
# check for errors, warnings, and lints.
#
# The issues identified by the analyzer are surfaced in the UI of Dart-enabled
# IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be
# invoked from the command line by running `flutter analyze`.
# The following line activates a set of recommended lints for Flutter apps,
# packages, and plugins designed to encourage good coding practices.
include: package:flutter_lints/flutter.yaml
linter:
# The lint rules applied to this project can be customized in the
# section below to disable rules from the `package:flutter_lints/flutter.yaml`
# included above or to enable additional rules. A list of all available lints
# and their documentation is published at https://dart.dev/lints.
#
# Instead of disabling a lint rule for the entire project in the
# section below, it can also be suppressed for a single line of code
# or a specific dart file by using the `// ignore: name_of_lint` and
# `// ignore_for_file: name_of_lint` syntax on the line or in the file
# producing the lint.
rules:
# avoid_print: false # Uncomment to disable the `avoid_print` rule
# prefer_single_quotes: true # Uncomment to enable the `prefer_single_quotes` rule
# Additional information about this file can be found at
