# This function is executed with a redirect that pipes the source of
# this script into file descriptor 3.
#
# 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 Mac.
# There is not a direct equivalent, so on platforms that don't have flock,
# we fall back to using a lockfile and spinlock with "shlock". This
# doesn't work as well over NFS as it relies on PIDs. Any platform
# without either of these tools has no locking at all. To determine if we
# have "flock" or "shlock" available, we abuse the "hash" shell built-in.
#
# The second complication is NFS. On NFS, to obtain an exclusive
# lock you need a file descriptor that is open for writing, because
# NFS implements exclusive locks by writing, or some such. Thus, we
# ignore errors from flock. We do so by using the '|| true' trick,
# since we are running in a 'set -e' environment wherein all errors
# are fatal, and 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.
#
# For "flock", the lock is released when the file descriptor goes out of
# scope, i.e. when this function returns. The lock is released via
# a trap when using "shlock".

注意新建的文件名中不能是小驼峰，两个单词之间要用下划线链接
flutter create melon_app
cd myapp
官网说这个指令会生成melon_app文件夹，文件夹下会有一个基础的小项目，核心文件是在lib/main.dart，可是我测试没有成功，日常摊手.jpg
flutter devicesflutter runlockfile文件
F1键之后，再输入flutter，选择Flutter: New Project
Enter键，注意输入的文件夹名称不能包含驼峰命名，如果输入名称包含驼峰，输入框会标红提示。这边提示安装dart, https://www.dartlang.org/install
