convertDiagnosticMessage method

DiagnosticMessage convertDiagnosticMessage(DiagnosticMessage message, { LineInfo? lineInfo, })

Convert the diagnostic message from the 'analyzer' package to an analysis error defined by the plugin API. If a lineInfo is provided then the error's location will have a start line and start column.

Implementation

plugin.DiagnosticMessage convertDiagnosticMessage(
  analyzer.DiagnosticMessage message, {
  analyzer.LineInfo? lineInfo,
}) {
  var file = message.filePath;
  var offset = message.offset;
  var length = message.length;
  var startLine = -1;
  var startColumn = -1;
  var endLine = -1;
  var endColumn = -1;
  if (lineInfo != null) {
    var lineLocation = lineInfo.getLocation(offset);
    startLine = lineLocation.lineNumber;
    startColumn = lineLocation.columnNumber;
    var endLocation = lineInfo.getLocation(offset + length);
    endLine = endLocation.lineNumber;
    endColumn = endLocation.columnNumber;
  }
  return plugin.DiagnosticMessage(
    message.messageText(includeUrl: true),
    plugin.Location(
      file,
      offset,
      length,
      startLine,
      startColumn,
      endLine: endLine,
      endColumn: endColumn,
    ),
  );
}
