Consider using xml parser instead of json for parsing plist #62160
Description
Flutter tools rely on plutil to parse plist into json. I assume we do this because dart:core comes with json decoding support. Unfortunately, certain internal apps are picking up plist configuration that contains <data> tags which are not supported for json conversion.
I tried to extract certain key values but plutil isn't happy with these tags even if their specific conversion is not requested.
Sample plist:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>CFBundleDisplayName</key>
<string>Test (Dev)</string>
<key>CFBundleLocalizations</key>
<array>
<data>
828fnna
</data>
<string>ar</string>
<string>bg</string>
</array>
</dict>
</plist>[14:34] ~$ /usr/bin/plutil -convert json -o - ~/test.plist
/Users/mehmetf/test.plist: invalid object in plist for destination format
package:xml is not a heavy dependency so if we were willing to include it, we could sidestep this problem.
