This install step fails if the list is empty, which is the case for projects without plugins (or Dart-only plugins, so flutter/plugins presubmits are currently broken).

This reverts commit 3efc517a.

This reverts commit 1d407de9.

* Explicitly install the Flutter library

* Publish ${FLUTTER_LIBRARY} to parent scope

* Bundle plugin libraries

* Bundle <plugin_name>_bundled_libraries too

* BUNDLED_LIBRARIES -> PLUGIN_BUNDLED_LIBRARIES

* Update Linux plugin test

* Address review comments

[Flutter Driver] Update the comments regarding the default timeout of WaitFor and WaitForAbsent commands (#58771)

* add language version 2.8 in packages/flutter

* enable non-nullable analyzer flag

* combine forwardStandardStreams

* combine exec and eval

The original help info has lines too long for
appropriate terminal display.

This reverts commit dca6320f.
