The Flutter Inspector

The "Flutter Inspect" feature is a debugging tool in Flutter that allows developers to inspect the widget tree of their app, examine the layout and size of the widgets, and explore the app's state and dependencies. The Inspect feature is built into the Flutter framework, and is accessible through the Flutter: Inspect Widget option in the command palette of most IDEs (like Visual Studio Code or Android Studio) or by right-clicking on the app while it's running in the emulator and selecting 'Inspect Widget'

With the help of Inspect tool developer can visualise the widgets tree and its properties and state, and explore the tree structure to see how the widgets are nested, and how their properties and state are inherited. It also allows you to do some live editing of properties, which is extremely helpful to find the correct value of some properties in order to make the layout work correctly.

It's a valuable tool to debug the layout and look of the app.
