getKeyFromUserIfRequired function

Future<void> getKeyFromUserIfRequired(BuildContext context, Widget child)

Ask for the security key from the user if the security key is not available or cannot be verfied using the verification key stored in PODs.

Implementation

Future<void> getKeyFromUserIfRequired(
  BuildContext context,
  Widget child,
) async {
  if (await KeyManager.hasSecurityKey()) {
    return;
  } else {
    final verificationKey = await KeyManager.getVerificationKey();
    // Get the webId to display in the security key prompt.

    final webId = await getWebId();

    const inputKey = 'security_key';
    final inputField = (
      fieldKey: inputKey,
      fieldLabel: 'Security Key',
      validateFunc: (key) {
        assert(key != null);
        return verifySecurityKey(key as String, verificationKey)
            ? null
            : 'Incorrect Security Key';
      }
    );

    // Use the unified SecurityKeyUI widget with the appropriate configuration.

    final securityKeyInput = SecurityKeyUI(
      webId: webId,
      title: 'Security Key',
      message: SecurityStrings.securityKeyPrompt,
      inputFields: [inputField],
      formKey: GlobalKey<FormBuilderState>(),
      submitFunc: (formDataMap) async {
        await KeyManager.setSecurityKey(formDataMap[inputKey].toString());
        debugPrint('Security key saved');
        if (context.mounted) Navigator.pop(context);
      },
      child: child,
    );

    if (context.mounted) {
      await Navigator.push(
        context,
        MaterialPageRoute(builder: (context) => securityKeyInput),
      );
    }
  }
