getHover method

Future<String> getHover(int line, int character)

This method is used to get details at a specific position in the document.

This method is used internally by the CodeCrafter, calling this with appropriate parameters will returns a String. If the LSP server does not support hover or the location provided is invalid, it will return an empty string.

Implementation

Future<String> getHover(int line, int character) async {
  final response = await _sendRequest(
    method: 'textDocument/hover',
    params: _commonParams(line, character),
  );
  final contents = response['result']?['contents'];
  if (contents == null || contents.isEmpty) return '';
  if (contents is String) return contents;
  if (contents is Map && contents.containsKey('value')) {
    return contents['value'] ?? '';
  }
  if (contents is List && contents.isNotEmpty) {
    return contents
        .map((item) {
          if (item is String) return item;
          if (item is Map && item.containsKey('value')) return item['value'];
          return '';
        })
        .join('\n');
  }
  return '';
