flutter simple multiselect

Flutter Simple Multiselect #
v2.1.1
There are a few multiselect packages for flutter but somehow i haven't found one that is simple like this. It's inspired by the vue multiselect. You can use static or async (server) data and use it as searchable single or multiselect. Everything is customizable.
Note: This package is created on the backbone of Material Tag Editor.
Features #
Fetch and search async data directly from server or from static data. Use it for multiselect and single, and use it somehow naturally.

Usage #
Add the package to pubspec.yaml
