# cpd_2022_energy
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-lang.github.io/linter/lints/index.html.
#
# 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

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number is used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html
# In Windows, build-name is used as the major, minor, and patch parts
# of the product and file versions while build-number is used as the build suffix.

# To add assets to your application, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700

# For details regarding fonts from package dependencies,
