incorrect use of parentdatawidget
    ParentDataWidget is an important class in Flutter. It is used to promote a widget’s rendering data from an ancestor in the tree. Using ParentDataWidget incorrectly can result in serious issues in your app that can cause bugs and surprise behavior.
    One of the most common mistakes with ParentDataWidget is assigning it to a widget not in the same branch of the tree in which it has been declared. This can lead to unexpected results, as only widgets of the ParentDataWidget’s immediate ancestor and their descendants can use the data stored in it. This can also result in a ParentDataWidget not being applied to the desired widget, which can cause a series of issues in your app.
    Another mistake with ParentDataWidgets is that they are not updated with the widget tree. If the tree is changed, the previously assigned ParentDataWidget will remain unchanged, which can cause widgets to render incorrectly. To ensure that a ParentDataWidget is updated correctly, it must be reassigned every time the tree is changed.
    A third mistake with ParentDataWidget is that it can be easily applied to child widgets, instead of the parent widget. This is especially common when declaring the widget in the build method of the parent Widget. While doing so is not wrong per se, it can cause a widget that has not been declared in the root of the widget tree to be assigned the ParentDataWidget of the parent widget, which may cause unexpected issues.
    Finally, some developers tend to use ParentDataWidget as a way to pass data from one widget to another, instead of what it was designed for. While this may, in some cases, be useful, it is important to note that this does not use ParentDataWidget for the purpose for which is was created, and that a better approach will usually be found.

While it provides an efficient way to assign data to widgets, it is important that it is used correctly. By following the guidelines and making sure that it is applied correctly, developers can avoid most of the issues that could arise from its incorrect use.
