dart_app_data

Dart Package for getting commonly used locations for storage on Windows, Mac, and Linux, such as the app data directories.

Inspired by path_provider (this does the same, except for Dart CLI apps or libs).

Originally written for a locally cached repository (think .m2 cache for Java). Tested and working on Windows, Mac, and Linux. Flutter is not supported.

Notice

Not tested on Windows 7/Vista/older, this library could use improvements! It's also a bit overkill for what basically amounts to a Platform.is()... call and a simple string concatenation, so I am looking for ideas on features to add. You can also just take a look at Locator.dart and copy the code from there instead of pulling in the entire package.

How to Install

Add this to your package's pubspec.yaml file:

dependencies:
  dart_app_data: ^1.0.1

Usage

With AppData

import 'package:dart_app_data/dart_app_data.dart';
...

// Creates a folder if it does not already exist (only call once).
final myData = AppData.findOrCreate('.my_app');

// Get the location of the folder as a String
print(myData.path); // Outputs: C:\Users\MyUsername\AppData\Roaming\.my_app

// Get the location of the folder directly as a directory
print(myData.directory);

// Get the name of the cache
print(myData.name); // Outputs: .my_app

// ... Do whatever you want with the folder now.
// Want to delete it?
// myData.delete();

Without AppData

import 'package:dart_app_data/src/locator.dart';
...

// No need for the AppData abstraction? Use the Locator helper.
print(Locator.getPlatformSpecificCachePath()); 
// Outputs: C:\Users\MyUsername\AppData\Roaming

Troubleshooting

LocatorException: App caches are not supported for mobile devices

As the message says, this package is only for Dart applications that run on a traditional operating system (such as Windows, Linux, Mac).

LocatorException: The user application path for this platform ("$path") does not exist on this system

Something went wrong during the path discovery (i.e.: the path does not exist). Is the app running as root? Did you a delete a common path somehow (see below)? Submit an Issue if this persists.

LocatorException: Platform-specific cache path for platform "$os" was not found

This means you're on an unsupported operating system.

Paths

• Windows: C:\Users\MyUsername\AppData\Roaming
• macOS: /MyUsername/Library/Application Support
• Linux: /MyUsername/user/
