Add-to-app notes:
- The Flutter module must be added to the Android app via manual editing as in the add-to-app docs,
or by using the tool in Android Studio that generates a module and does the editing.
- The Flutter module may be in a directory nested under the Android app or it may be in a different
location entirely. IntelliJ supports both, and is moving toward the latter.
- Enabling co-editing means converting the Flutter module to a Gradle module and adding it to the
Android app as a sub-project.
o If the parent of the Flutter module root directory is the Android app
root directory, add "include ':flutterModule'" to the parent settings.gradle;
otherwise something like what add-to-app does to define the :flutter module is needed.
o Create a simple build.gradle in the Flutter module root directory.
o Add Android-Gradle and Android facets to the Idea module of the Flutter module.

#
# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt

## Flutter SDK dependency versions
The files in this directory specifies pinned versions of various
dependencies of the flutter SDK.
The `bin/internal/engine.version` file controls which version of the
Flutter engine to use. The file contains the commit hash of a commit
in the <https://github.com/flutter/engine> repository. That hash must
have successfully been compiled on
<https://build.chromium.org/p/client.flutter/> and had its artifacts
(the binaries that run on Android and iOS, the compiler, etc)
successfully uploaded to Google Cloud Storage.
The `/bin/internal/engine.merge_method` file controls how we merge a
pull request created by the engine auto-roller. If it's `squash`,
there's only one commit for a pull request no matter how many engine
commits there are inside that pull request. If it's `rebase`, the
number of commits in the framework is equal to the number of engine
commits in the pull request. The latter method makes it easier to
detect regressions but costs more test resources.
The `bin/internal/flutter_packages.version` file specifies the version
of the `flutter/packages` repository to be used for testing. The
`flutter/packages` repository isn't an upstream dependency of
`flutter/flutter`; it is only used as part of the test suite for
verification, and the pinned version here makes sure that tests are
deterministic at each `flutter/flutter` commit.

# Waits for an update lock to be acquired.
#
# To ensure that we don't simultaneously update Dart in multiple parallel
# instances, we try to obtain an exclusive lock on this file descriptor (and
# thus this script's source file) while we are updating Dart and compiling the
# script. To do this, we try to use the command line program "flock", which is
# available on many Unix-like platforms, in particular on most Linux
# distributions. You give it a file descriptor, and it locks the corresponding
# file, having inherited the file descriptor from the shell.
#
# Complicating matters, there are two major scenarios where this will not
# work.
#
# The first is if the platform doesn't have "flock", for example on macOS. There
# is not a direct equivalent, so on platforms that don't have flock, we fall
# back to using trying to use the shlock command, and if that doesn't exist,
# then we use mkdir as an atomic operation to create a lock directory. If mkdir
# is able to create the directory, then the lock is acquired. To determine if we
# have "flock" or "shlock" available, we use the "hash" shell built-in.
#
# The second complication is on network file shares. On NFS, to obtain an
# exclusive lock you need a file descriptor that is open for writing. Thus, we
# ignore errors from flock by redirecting all output to /dev/null, since users
# will typically not care about errors from flock and are more likely to be
# confused by them than helped. The "shlock" method doesn't work for network
# shares, since it is PID-based. The "mkdir" method does work over NFS
# implementations that support atomic directory creation (which is most of
# them). The "schlock" and "flock" commands are more reliable than the mkdir
# method, however, or we would use mkdir in all cases.
#
# The upgrade_flutter function calling _wait_for_lock is executed in a subshell
# with a redirect that pipes the source of this script into file descriptor 7.
# A flock lock is released when this subshell exits and file descriptor 7 is
# closed. The mkdir lock is released via an exit trap from the subshell that
# deletes the lock directory.
