getTokenBalance method

Implementation

@override

    final response = await http.get(url, headers: _requiredHeaders);
    _core.logger.i('[$runtimeType] getTokenBalance => ${response.body}');

    final balances = _handleResponse<Map<String, dynamic>>(
      response: response,
      parser: (body) => jsonDecode(body) as Map<String, dynamic>,
      errorContext: 'getTokenBalance',

    _tokensList = (balances['balances'] as List)

        .toList();
