This README describes the package. If you publish this package to pub.dev,
|
||||||
|
this README's contents appear on the landing page for your package.
|
||||||
|
|
||||||
|
For information about how to write a good package README, see the guide for
|
||||||
|
[writing package pages](https://dart.dev/guides/libraries/writing-package-pages).
|
||||||
|
|
||||||
|
For general information about developing packages, see the Dart guide for
|
||||||
|
[creating packages](https://dart.dev/guides/libraries/create-library-packages)

TODO: Put a short description of the package here that helps potential users
|
||||||
|
know whether this package might be useful for them.
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
TODO: List what your package can do. Maybe include images, gifs, or videos.
|
||||||
|
|
||||||
|
## Getting started
|
||||||
|
|
||||||
|
TODO: List prerequisites and provide or point to information on how to
|
||||||
|
start using the package.
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
TODO: Include short and useful examples for package users. Add longer examples
|
||||||
|
to `/example` folder.
|
||||||
|
|
||||||
|
```dart
|
||||||
|
const like = 'sample';
|
||||||
|
```
|
||||||
|
|
||||||
|
## Additional information
|
||||||
|
|
||||||
|
TODO: Tell users more about the package: where to find more information, how to
|
||||||
|
contribute to the package, how to file issues, what response they can expect
|
||||||
|
from the package authors, and more.

# This file configures the static analysis results for your project (errors,
|
||||||
|
# warnings, and lints).
|
||||||
|
#
|
||||||
|
# This enables the 'recommended' set of lints from `package:lints`.
|
||||||
|
# This set helps identify many issues that may lead to problems when running
|
||||||
|
# or consuming Dart code, and enforces writing Dart using a single, idiomatic
|
||||||
|
# style and format.
|
||||||
|
#
|
||||||
|
# If you want a smaller set of lints you can change this to specify
|
||||||
|
# 'package:lints/core.yaml'. These are just the most critical lints
|
||||||
|
# (the recommended set includes the core lints).
|
||||||
|
# The core lints are also what is used by pub.dev for scoring packages.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
# Uncomment the following section to specify additional rules.

|
|
