dynamic show(BuildContext context, { String? message, bool isDismissible = kDebugMode, ThemeData? theme, required ProImageEditorConfigs configs, })

Displays a loading dialog in the given context.

• message is an optional parameter to customize the loading message.
• isDismissible determines if the dialog can be dismissed.
• theme is the theme data for styling the dialog.
• imageEditorTheme is the theme specific to the image editor.
• designMode specifies the design mode for the image editor.
• i18n provides internationalization support.

Returns a Future that completes when the dialog is dismissed.
