clientViaUserConsent method

Future<AutoRefreshingAuthClient> clientViaUserConsent({
  1. bool immediate = false,
  2. String? loginHint,
  3. String? hostedDomain,

Obtains AccessCredentials and returns an authenticated HTTP client.

HTTP requests made on the returned client will get an additional Authorization header with the AccessCredentials obtained. Once the AccessCredentials expire, it will use it's refresh token (if available) to obtain new credentials. See autoRefreshingClient for more information.

See obtainAccessCredentialsViaUserConsent for how credentials will be obtained. Errors from obtainAccessCredentialsViaUserConsent will be let through to the returned Future of this function and to the returned HTTP client (in case of credential refreshes).

The returned HTTP client will forward errors from lower levels via it's Future<Response> or it's stream.

If immediate is true there will be no user involvement. If the user is either not logged in or has not already granted the application access, a UserConsentException will be thrown.

If immediate is false the user might be asked to login (if not already logged in) and might get asked to grant the application access (if the application hasn't been granted access before).

The user is responsible for closing the returned HTTP Client.

If loginHint is not null, it will be passed to the server as a hint to which user is being signed-in. This can e.g. be an email or a User ID which might be used as pre-selection in the sign-in flow.

If provided, restricts sign-in to Google Apps hosted accounts at hostedDomain. For more details, see
