夏天的飞鸟，飞到我的窗前唱歌，又飞去了。
秋天的黄叶，它们没有什么可唱，只叹息一声，飞落在那里。
Stray
birds
of
summer
come
to
my
window
to
sing
and
fly
away.
And
yellow
leaves
of
autumn,
which
have
no
songs,
flutter
and
fall
there
with
a
sign.

世界上的一队小小的漂泊者呀，请留下你们的足印在我的文字里。
O
Troupe
of
little
vagrants
of
the
world,
leave
your
footprints
in
my
words.

世界对着它的爱人，把它浩翰的面具揭下了。
它变小了，小如一首歌，小如一回永恒的接吻。
The
world
puts
off
its
mask
of
vastness
to
its
lover.
It
becomes
small
as
one
song,
as
one
kiss
of
the
eternal.

是大地的泪点，使她的微笑保持着青春不谢。
It
is
the
tears
of
the
earth
that
keep
here
smiles
in
bloom.

无垠的沙漠热烈追求一叶绿草的爱，她摇摇头笑着飞开了。
The
mighty
desert
is
burning
for
the
love
of
a
bladeof
grass
who
shakes
her
head
and
laughs
and
flies
away.

如果你因失去了太阳而流泪，那么你也将失去群星了。
If
you
shed
tears
when
you
miss
the
sun,
you
also
miss
the
stars.

跳舞着的流水呀，在你途中的泥沙，要求你的歌声，你的流动呢。你肯挟
瘸足的泥沙而俱下么？
The
sands
in
your
way
beg
for
your
song
and
your
movement,
dancing
water.
Will
you
carry
the
burden
of
their
lameness?
透明视频动画是目前比较流行的实现动画的一种, 大厂也相继开源自己的框架，最终我们选中 腾讯vap ，它支持了Android、IOS、Web，为我们封装flutter_vap提供了天然的便利，并且它提供了将帧图片生成带alpha通道视频的工具，这简直太赞了。
VAP（Video Animation Player）是企鹅电竞开发，用于播放酷炫动画的实现方案。

1，执行 flutter pub publish--dry-run 检查是否具备发布条件
遇到的问题1：
It‘s strongly recommended to include a “homepage“ or “repository“ field
解决方案：在 pubspec. yaml 中配置 主页 homepage 地址 :
homepage:
可参考：
2，执行 flutter pub publish--server= 发布
如果执行flutter pub publish发布的话会遇到以下错误，国内还是用 flutter pub publish--server= 来发布
package repository requested authentication! You can provide credential using:pub token add
问题1：It looks like accounts.google.com is having some trouble. Pub will wait for a while before trying to connect again. OS Error: Operation timed out, errno = 60, address = accounts.google.com, port = 53481 pub finished with exit code 69
原因：
1、国内墙；
2、flutter环境配置添加了国内镜像
解决方式：
1、翻墙；
2、屏蔽环境变量里关于flutter的国内镜像；
屏蔽方式如下：
# export PUB_HOSTED_URL=
# export FLUTTER_STORAGE_BASE_URL=
3、设置终端代理命令(这个是我解决的方式)，这个非常重要，不然就会报上面超时错误了
如果出现：Flutter pub finished with exit code 1
解决方式：flutter packages pub publish --server=
此问题原文链接：（毕竟要尊重版权）
问题2：LICENSE这个文件中不能有TODO，也不能为空，可找个flutter库看看别人是怎么写的
