* Update project.pbxproj files to say Flutter rather than Chromium Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright. * Update the copyright notice checker to require a standard notice on all files * Update copyrights on Dart files. (This was a mechanical commit.) * Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine. Some were already marked "The Flutter Authors", not clear why. Their dates have been normalized. Some were missing the blank line after the license. Some were randomly different in trivial ways for no apparent reason (e.g. missing the trailing period). * Clean up the copyrights in non-Dart files. (Manual edits.) Also, make sure templates don't have copyrights. * Fix some more ORGANIZATIONNAMEs

// This program replaces the material_kn.arb and cupertino_kn.arb
|
|
// files in flutter_localizations/packages/lib/src/l10n with versions
|
|
// where the contents of the localized strings have been replaced by JSON
|
|
// escapes. This is done because some of those strings contain characters
|
|
// that can crash Emacs on Linux. There is more information
|
|
// here: https://github.com/flutter/flutter/issues/36704 and in the README
|
|
// in flutter_localizations/packages/lib/src/l10n.
|

//
|
|
// This app needs to be run by hand when material_kn.arb or cupertino_kn.arb
|
|
// have been updated.
|
|
//
|
|
// ## Usage
|
|
//
|
|
// Run this program from the root of the git repository.
|
|
//
|
