# shared_preferences_example |
||||
|
||||
Demonstrates how to use the shared_preferences plugin. |
||||
|
||||
## 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 |

# 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 |
