Change `ngFor=“#…”` to `ngFor=“let…` in code. All are .dart files except for `app_component.html` which also has changes for: - `<inpuf var-foo…`> to `<input ref-foo…>` - `#docregion` tag name updates from var-foo to ref-foo. - Other misc updates to minimize diffs with TS version of file, whitespace differences were ignored. + Minor update to sync up Dart prose with TS prose. + Used https://github.com/angular/angular/wiki/Angular-2-Dart-Transformer#resol ved_identifiers to solve https://github.com/angular/angular.io/issues/1033 Guide/pipes not updated as it will be rolled back to beta.15 in PR #1220.
