Yes; they are several ways to do so:

- install a Spotlight metadata importer (or an application that includes one) that handles this file type. As dart files are probably plain text files, this is probably not necessary though.

- install an application (e.g. an IDE or text editor) that declares the .dart file type as conforming to the UTI (Uniform Type Identifier) public.source-code or public.plain-text.

- in last resort, there is a command line setting in FoxTrot to make it index a specific file type as another one; first quit FoxTrot, then type the following command to a Terminal.app window:

defaults write com.ctmdev.foxtrot Aliases -array-add "{type='dart'; as='txt';}"

You will then have to rebuild your index.

I have tried two of them, but foxtrot still does not index the .dart [plain
text] files. I guess the main cause is .dart extension is registered by mac
system as "DART disk image", so foxtrot does not index them,
please visit the follow link for .dart detail.
https://github.com/dart-lang/sdk/issues/28205 .dart files are treated as
disk images (security sensitive) on Macs
https://support.apple.com/kb/TA29157?locale=en_US&viewlo cale=en_US
I have tried:
1.in a Terminal.app window: defaults write com.ctmdev.foxtrot Aliases
-array-add "{type='dart'; as='txt';}"
2Iinstalled visual studio code change .dart file type to always open with
visual studio code.

I don't know how to write a Spotlight metadata importer for dart. and
.dart is a plain text file.
Would you please help me index .dart file thank you.

I find a solution to this:


Rebuilding the LaunchService database can be done by running a command in a
Terminal:

/System/Library/Frameworks/CoreServices.framework/Versions/A /Frameworks/LaunchServices.framework/Versions/A/Support/lsre gister
-kill -r -domain local -domain system -domain user

and then rebuild index.

This should have worked. Make sure that:
- FoxTrot is not running when you enter the command
- the command is typed or pasted as a single line, followed by a return
- the FoxTrot index needs to be rebuilt afterwards

Telling the Finder to open .dart files with a specific application is not enough; the application has to define the file extension in its info.plist file, and declare that it is a source code file; something like this:

UTExportedTypeDeclarations


UTTypeIdentifier
public.dart-source
UTTypeDescription
Dart source file
UTTypeConformsTo

public.source-code

UTTypeTagSpecification

public.filename-extension

dart





However, if this conflicts with a type declaration of another application (DiskImageMounter, in the case of dart, which associates the .dart extension to the com.apple.disk-image-dart UTI), then rebuilding the LaunchService database might be necessary, but I am not sure how this conflict will be arbitrated. Anyway, method 1 above should always work, independently of these LaunchServices considerations.

Additionally, there is yet another way to force some files to be indexed as plain text: set their HFS filetype to 'TEXT'. Kinda deprecated, but still working.
