To see more examples, just start the Example App and use the DropDown to test all type of widgets.

Supported Widgets #

• ReorderableWrap
• ReorderableGridView
• ReorderableGridView.count
• ReorderableGridView.extent

Additional information #

ReorderableWrap and ReorderableGridView are just an extension of the known widgets Wrap and GridView.

The extension includes the functionality to reorder their items.

Be careful that you don't forget to reorder your children when you reorder your items to prevent weird bugs. Also you have to add a unique key for every child in your list.

In the following description you get information about the new parameters.

More information about the parameters of GridView and Wrap are on the flutter documentation.

Future Plans #

Currently, I didn't implement all types of GridView.

Also there is an animation when removing or adding items but currently you cannot decide your preferred animation.

And the code could be more readable and less complex, so in the future I might refactor the code a bit more.

If you have feature requests or found some issues, feel free and open your issues in the GitHub project.

Thank you for using this package.
