Example 6 with DiagnosticsNode

use of io.flutter.inspector.DiagnosticsNode in project flutter-intellij by flutter.

the class InspectorTreeMouseListener method mouseClicked.

    // property.

    if (diagnostic != null && !diagnostic.isProperty()) {
        // A double click triggers forcing changing the subtree root.
