useAppCacheDir static method
If running from Flutter, the base directory will be the application's cache directory. If running from tests, it will use the system's temp directory.
Implementation
static Future<void> useAppCacheDir() async {
if (_baseDirectory != null) return;
if (_fileSystem == const LocalFileSystem()) {
try {
_baseDirectory = await getApplicationCacheDirectory();
} on MissingPluginException catch (_) {
_baseDirectory = const LocalFileSystem().systemTempDirectory;
}
} else
_baseDirectory = _fileSystem.systemTempDirectory;
}
