If a file scheme and one or more roots is provided, fall back to this mapping before the direct file path if the file path cannot be turned into a package URI.

Use URI representation so that the transformation is resilient to the org-dartlang-app scheme used by the web builds.

If a file scheme and one or more roots is provided, fall back to this mapping before the direct file path if the file path cannot be turned into a package URI.

Fixes #66095

Fixes additional bugs uncovered by tester, style fixes to prevent suggested imports.

Suppress compilation errors on startup so they are not duplicated from the native build step.

* Revert "[flutter_tools] Put a heap size limit on the frontend_server (#58039)"

[flutter_tools] Apply --no-causal-async-stacks and --lazy-async-stacks to profile/release builds (#49377)

* 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

* implicit-casts:false on flutter_tools

* use castStringKeyedMap

* address review comments

* address review comments

* fix issues after rebase

Fixes various Flutter framework test failures when bytecode is enabled.

Bytecode generation will otherwise omit assert code, causing --enable-asserts to have no effect in the VM.
