Actually the fix is quite simple : go in your Flutter SDK path, then in .pub-cache\hosted\pub.dartlang.org\flutter_svg-0.18.1\lib\src, and edit "picture_provider.dart".
Inside (line 50), replace :
context != null ? Localizations.localeOf(context) : null,
with :
context != null ? Localizations.localeOf(context, nullOk: true) : null,

Might sometime be in %LOCALAPPDATA%\Pub\Cache, but it's just a guess : I'm a total noob with Flutter... ;)
