Custom dartfmt / dart format / flutter format

A quick and (relatively) easy tutorial on how to use a customised dart formatter in your dart/flutter project!

Currently works only in VSCode

What you'll need:

• VSCode editor
• A dart/flutter project
• This extension, or if it's no longer available, any kind of Run-On-Save extension will do, you'll just have to customize the .vscode/settings.json file for it.

What you need to do:

• Clone the https://github.com/dart-lang/dart_style to your pc
• Make edits to whatever you need. (A good idea is to search commits, since then you will just need to revert the changes)
• Compile it using dart compile exe bin/format.dart - it will produce an format.exe file in the bin folder.
• Move the format.exe file to your project directory in the .vscode folder, and rename it to dartfmt.exe
• Copy the settings from .vscode/settings.json to your files, and edit it to your preferences. (Remember: the number after -l in the 7th line is the max line length)
• Check whether the Dart SDK compiler is disabled in VSCode settings!
• You're ready to go!

Additional notes:

• I needed it to stop forcing a blank line after functions, so I went and found this commit, and forced the needsDouble variables to false.
• Yes, I know the current method is a bit janky, but simply writing to the same file creates endless problems, and I couldn't find any better method. If you find one, feel free to share it!
