[Linux] Fails to build

[Casuallynoted]

I'm getting the following errors when running the suggested build steps on Linux, I currently have the Flutter SDK and Android Studio installed.

cas@Framework:~/miria$ flutter pub get
"ja_OJ": 425 untranslated message(s).
To see a detailed report, use the untranslated-messages-file 
option in the l10n.yaml file:
untranslated-messages-file: desiredFileName.txt
<other option>: <other selection> 


This will generate a JSON format file containing all messages that 
need to be translated.

I think it is a flutter-snap issue.
The easiest way to solve this problem is to install the Flutter SDK manually.

Unfortunately after a manual flutter install, I am getting:

You need to install libsecret-1-dev and libmpv-dev (this is written in Japanese in the Wiki but not in the README yet, sorry).

sudo apt install libsecret-1-dev libmpv-dev

Was the build successful?
