clearOnInstall method
void
clearOnInstall()
Wipes stored credentials on the first launch after a (re)install.
iOS keeps keychain items across an uninstall, so a reinstalled app could otherwise start "logged in" with a stale session. Call it once at startup, before the first request; it does nothing after the first run, and — unlike deleteToken — never notifies listeners.
Implementation
void clearOnInstall() async {
final _hasRunBefore = await _prefs.getBool(_hasRunBeforeKey) ?? false;
if (!_hasRunBefore) {
_storage.deleteAll();
await _prefs.setBool(_hasRunBeforeKey, true);
}
}
