Update for Twig 3

[slokhorst]

Fixes #6

[koelle25]

Yes, thanks for this @slokhorst !

@kanellov Can you please merge this/release a new version (probably new major bc this is a breaking change)?

[koelle25]

Oh, @slokhorst , maybe you can update the twig requirement in composer.json to ^3.0 and add it to this PR.

[slokhorst]

@koelle25 I think these new class names were backported to the 1.x and 2.x branches too (commit):

And see also the changelog.

So it seems to be ^1.34.0 || ^2.4.0 || ^3.0.0, although I've not tested the 1.x and 2.x branches myself.

I copied the class with the modifications in the PR into my Slim Framework 4 app alongside Twig 3, and this works quite nicely. A merge would be splendid. Thanks!

bump

I forked it and fixed compatibility with slim/flash 0.4.

To use it in your composer add the following:

{
  "repositories": [
    {
      "url": "https://github.com/winteragency/slim-twig-flash.git",
      "type": "git"
    }
  ],
  "require": {
    "kanellov/slim-twig-flash": "dev-master"
  }
}
