token method

Future<OAuthTokenResponse?> token(String grantType, { String? code, String? redirectUri, String? clientId, String? clientSecret, String? codeVerifier, String? refreshToken, String? scope, })

Token endpoint

Exchanges an authorization code for tokens, or refreshes tokens. Supports grant types: - authorization_code: Exchange code for tokens - refresh_token: Refresh access token - client_credentials: Get tokens for a confidential client

Parameters:

• String grantType (required):

• String code: Authorization code (for authorization_code grant)

• String redirectUri: Redirect URI (must match the one used in authorization)

• String clientId:

• String clientSecret: Client secret (for confidential clients)

• String codeVerifier: PKCE code verifier

• String refreshToken: Refresh token (for refresh_token grant)

• String scope: Requested scopes

Implementation

Future<OAuthTokenResponse?> token(String grantType, { String? code, String? redirectUri, String? clientId, String? clientSecret, String? codeVerifier, String? refreshToken, String? scope, }) async {
  final response = await tokenWithHttpInfo(grantType,  code: code, redirectUri: redirectUri, clientId: clientId, clientSecret: clientSecret, codeVerifier: codeVerifier, refreshToken: refreshToken, scope: scope, );
  if (response.statusCode >= HttpStatus.badRequest) {
    throw ApiException(response.statusCode, await _decodeBodyBytes(response));
  }
  // When a remote server returns no body with a status of 204, we shall not decode it.
  // At the time of writing this, `dart:convert` will throw an "Unexpected end of input"
  // FormatException when trying to decode an empty string.
  if (response.body.isNotEmpty && response.statusCode != HttpStatus.noContent) {
    return await apiClient.deserializeAsync(await _decodeBodyBytes(response), 'OAuthTokenResponse',) as OAuthTokenResponse;

  }
  return null;
