Unable to build with Flutter 2.2.2

[mirryi]

I'm unable to build the application on Flutter version 2.2.2. This is my first time working with Flutter, so I could be doing something wrong.

flutter pub get isn't able to resolve dependencies due to a conflict in dependency requirements between image and integration_test:

Running "flutter pub get" in xkcdviewer_...
Because every version of integration_test from sdk depends on archive 3.1.2 and image 2.1.19 depends on archive ^2.0.0, integration_test from sdk is incompatible with image 2.1.19.

And because no versions of image match >2.1.19 <3.0.0, integration_test from sdk is incompatible with image ^2.1.19.

So, because xkcd depends on both image ^2.1.19 and integration_test any from sdk, version solving failed.
pub get failed (1; So, because xkcd depends on both image ^2.1.19 and integration_test any from sdk, version solving
failed.)

Upgrading image to the latest version, 3.0.2 seems to resolve this, but there are tons of build errors after that: https://hastebin.com/raw/onaciwixut

flutter pub upgrade seems to fix everything, except an error in dynamic_theme:

Try correcting the name to the name of an existing method, or defining a method named 'ancestorStateOfType'.

This seems to be related to dynamic_theme #52? There is an unmerged PR that addresses this issue.

Hi, @Dophin2009, I intended to upgrade this project to a recent Flutter version and update the codebase with null safety but never had the drive to do so.
I'd be happy if you'd want to adopt xkcdViewer! Otherwise please consider this app as obsolete.

Sorry for not replying sooner.

No problem at all. Given my lack of much experience at all with flutter, I probably wouldn't be able to adopt this project, but I do want to get it upgraded and working! Thanks for creating and maintaining this up to this point.
