void inspectFromDiagnostic (dynamic diagnostics, Node parent) @visibleForTesting

Converts an diagnostics tree into a Node tree Creates a Node with Inspect data based on what information was in the DiagnosticsNode and attaches it to the parent

    /// property is titled "widget"

  // If the name of the child does not exist log it and skip that node
  if(name == ''){
    print('Name of node cannot be found');

  // Adds a hashcode to the name of the node so that the widgets with the same
  // names do not get their properties merged.
  var childNode = parent.child('${name}_${diagnostics.hashCode}');

  /// For each property, add the property to the node.
  for (DiagnosticsNode diagNode in diagnostics.getProperties()) {
    /// If the property isn't null, then get the name of the property
    /// and assign its value. The value of the property can be null
    /// but the property itself cannot be null.
