Nest files in Flutter projects on VSCode, inspired from https://github.com/antfu/vscode-file-nesting-config

settings.json

"explorer.fileNesting.enabled": true,
"explorer.fileNesting.expand": false,
"explorer.fileNesting.patterns": {
    "pubspec.yaml": ".flutter-plugins, .packages, .dart_tool, .flutter-plugins-dependencies, .metadata, .packages, pubspec.lock, build.yaml, analysis_options.yaml, all_lint_rules.yaml",
    ".gitignore": ".gitattributes, .gitmodules, .gitmessage, .mailmap, .git-blame*",
    "readme.*": "authors, backers.md, changelog*, citation*, code_of_conduct.md, codeowners, contributing.md, contributors, copying, credits, governance.md, history.md, license*, maintainers, readme*, security.md, sponsors.md",
    "*.dart": "$(capture).g.dart, $(capture).freezed.dart",
},

it worked for me, I was adding this first in my snippet area "dart.json" file now i have added this snippet in the right json file you have to search in the VScode search bar settings.json file it will show default settings.json file select that and paste above rules inside delimeters
if it gives error then
".....": "You other settings", "explorer.experimental.fileNesting.enabled": true, "explorer.experimental.fileNesting.expand": false, "explorer.experimental.fileNesting.patterns": { "pubspec.yaml": ".flutter-plugins, .packages, .dart_tool, .flutter-plugins-dependencies, .metadata, .packages, pubspec.lock, build.yaml, analysis_options.yaml, all_lint_rules.yaml", ".gitignore": ".gitattributes, .gitmodules, .gitmessage, .mailmap, .git-blame*", "readme.*": "authors, backers.md, changelog*, citation*, code_of_conduct.md, codeowners, contributing.md, contributors, copying, credits, governance.md, history.md, license*, maintainers, readme*, security.md, sponsors.md", "*.dart": "$(capture).g.dart, $(capture).freezed.dart", }, "........": "You other settings"

I have removed the delimeters added by the @gaetschwartz in the starting and in the end

hope it will help you....😊😊

it is giving me EOF error in json

@proismailshah you need add these line inside your settings.json file, so:

{
    ".....": "You other settings",
    "explorer.experimental.fileNesting.enabled": true,
    "explorer.experimental.fileNesting.expand": false,
    "explorer.experimental.fileNesting.patterns": {
        "pubspec.yaml": ".flutter-plugins, .packages, .dart_tool, .flutter-plugins-dependencies, .metadata, .packages, pubspec.lock, build.yaml, analysis_options.yaml, all_lint_rules.yaml",
        ".gitignore": ".gitattributes, .gitmodules, .gitmessage, .mailmap, .git-blame*",
        "readme.*": "authors, backers.md, changelog*, citation*, code_of_conduct.md, codeowners, contributing.md, contributors, copying, credits, governance.md, history.md, license*, maintainers, readme*, security.md, sponsors.md",
        "*.dart": "$(capture).g.dart, $(capture).freezed.dart",
      },
    "........": "You other settings"
}

Thanks @gaetschwartz

if your vs code did not recognize explorer.experimental.fileNesting.enabled you need to update it to the last version.

Thanks.

worked for mee.. see the location & process.. don't forget to add comma(,)

it really does work

as of v1.67.0, we can remove the experimental tag.

add pubspec_overrides.yaml to the list

can I add that iml file to the file nesting? and how to do it?

yes, you can.
just add the file name x.iml to pubspec.yaml list in the snippet
