In testing, I saw that _added_ files were not being analyzed at all by
plugins. It turned out that `PluginManager.broadcastWatchEvent` uses
that glob to decide if watch events should be broadcast to a given
plugin isolate. It uses this Glob to determine that answer:
```dart
Glob(
_resourceProvider.pathContext.separator,
pattern,
).matches(filePath)
```
and using `'*.dart'` for that pattern, always answers "no, this file
does not match '*.dart'"; I believe `**.dart` is the correct glob
pattern we should use.
