ngdart 1.1.0

[1.1.0] - 2021-12-25

Fixed

• Fix outdated project template.
• Fix inconsistent extra lines when error occurs.
• Back to null safety.

Removed

• Remove build and serve command. Very hard to maintain & build a global package that uses null-safety itself but contains some unsound-null-safety code. For example, dart pub global activate will always build the package in null-safety mode if the pubspec version is 2.12+, but webdev can't build under that.
