[BREAKING] Upgrade react-dropzone to version 10

[panz3r]

This PR upgrade react-dropzone to version 10.2.1 and updates the implementation to match the new component usage.

This PR introduce a breaking change since react-dropzone v10+ dropped support for react versions older than v16.8 (see release notes here).

Also this PR drops support for material-ui version 3.

I'd suggest this to be a major version bump for material-ui-dropzone (so bump to version 3.0.0) and, if support for older versions of react and material-ui is still required, you can think to keep a v2 branch with the previous implementation so that users of this library can decide to use v2.x or v3.x based on their needs whilst keep them updated independently (I think that many features/fixes can be ported from one version to the other with little to no effort).

@Yuvaleros can you look into this? Actually, @panz3r is bringing a lot of movement into this library and it could use a bit of love.

Hi @Yuvaleros ,

Thanks for inviting me as a Collaborator to this project, I'll try my best to keep this project as updated as possibile.

I recently merged my previous PR #119 , bumped the version number and made a tag (v.2.5.0) that can be released, that would be the latest version to support older react version (less than 16.8).

I'll also merge this PR soon and then proceed to rebase all my other PRs.

Hi @panz3r ,

Thanks for all the help and effort, I really appreciate it!

I published a version today to NPM - 2.5.0, with various merged PR's. Is it possible to change the tag to 2.6.0 and I'll release another one?

Of course, actually I just created the v2.x branch to keep working on the backward-compatible version (the one based on [email protected]) and bumped the version to 2.5.1 (just a patch is enough for that)

master branch already contains the code based on [email protected] which is no longer compatible with react versions lower than 16.8 (which I marked as v3.0.0 😬 ).

@Yuvaleros ,

You can publish version 2.5.1 by checking out that branch.

I'd wait to release version 3.0.0 after merging PR #121 and maybe others as well.

@panz3r ,

Reviewed and merged the relevant PR. Great stuff!

Maybe we should add a few lines to the README warning that react versions lower than 16.8 are no longer supported and that version 2.x.x should be used, WDYT?

Yeah, I think it's a great idea, I'd add a support table like this

version	react	material-UI
3.x	16.8+	4.x
2.x	15.x or 16.x	3.x or 4.x

@Yuvaleros ,

As suggested I added the above support table to both the README and the generated docsite.
