Entering opening brace causes code snippet suggestions to appear

Describe the bug When typing out a {, instead of just auto-completing the other }, it also pops up the dart code snippets so if you just hit enter you’ll insert the first code snippet instead of simply entering a new line to start typing inside your new set of braces.

To Reproduce

1. Open any dart file.
2. Enter a {
3. Hit enter

Expected behavior It should not show any snippet suggestions.

I don’t think there’s anything Dart-Code can do here. It seems like the triggerCharacters set up for Dart’s completion are causing VS Code to also show user snippets. Since triggerCharacters don’t have any context, they always fire unconditionally and any context must be handled by the server/completion provider. In this case, that is VS Code’s snippet handler.

There’s a similar issue at https://github.com/microsoft/vscode/issues/65200 and the suggestion is to set "editor.snippetSuggestions": "none". I suspect "editor.suggestOnTriggerCharacters": false, will also work, although both may disable functionality you might want.

Looks like there was a VS Code change that caused this - see https://github.com/microsoft/vscode/issues/136611#issuecomment-975769359. It’s planned to be fixed in the next release.
