PanelAutoSizing class Null safety

If provided, the panel's height will be automatically calculated based on the content. This technically modifies the PanelSize parameter as the panel's content size after panel is created. Also repeats this process when resolution of device changes. (e.g., Orientation change).

Note that even by setting this, please don't omit the PanelSize parameter. If the height is not calculatable, PanelSize parameters will be used.

Any height is maximum to screen size.

If this is used, when using a scrollable element, make sure it is shrinked. (e.g., When using ListView, set its shrinkWrap: true, when using Column, set its mainAxisSize: MainAxisSize.min). This is applicable to any level of the children. (e.g., Column inside Container...).

Moreover, take care when using Center widget, as that takes full space of parent and that's why it is not suggested to use.

If the PanelContent.panelContent contains more number of items, PanelSize.expandedHeight] is set to 1.0 (100% of available height).

While using this, you can not change height of the panel runtime.

Although tested, this feature can't be considered to be Super Stable. This also introduces a small processing overhead while calculating the height. When opting for production release of your app, please test the app thoroughly while using this.
