Breaking changes

4.2.0 had to introduce another breaking change, sorry. While 4.1.0 solved the problem for web users, it created a regression for some other people who author multiplatorm apps where not all variants are web-based. Instead of returning a web.File directly, the onDrop variants now return a DropzoneFileInterface. You can go on accessing its properties as before, so you might not even notice the difference.

4.1.0 deprecates onDrop and all other functions using dynamic type because the newer Flutter JS support enforces stricter type checking. onDrop will be removed in a coming version. Use onDropFile and onDropString instead.

4.0.x is compatible with Flutter 3.13 (stable) and later. If you're not yet ready to upgrade from a previous version of Flutter, stay with the latest 3.0.x version of flutter_dropzone. See the README of the web implementation for details.

3.0.x is compatible with Flutter 2.5 (stable) and later. If you're not yet ready to upgrade from a previous version of Flutter, stay with the latest 2.0.x version of flutter_dropzone. See the README of the web implementation for details.
