Conflicts and compatibility with different flutter versions

[xiaobeibeinihao]

环境：Flutter 1.5.4-hotfix.2 , Dart 2.3.0
git apply --3way /Users/cuikuangye/rong360work/androiddemo/aspectd-master/0001-aspectd.patch 我在执行这个命令行的时候报错：
error: patch failed: packages/flutter_tools/lib/src/commands/build_aot.dart:5
error: repository lacks the necessary blob to fall back on 3-way merge.
error: packages/flutter_tools/lib/src/commands/build_aot.dart: patch does not apply
error: patch failed: packages/flutter_tools/lib/src/commands/build_bundle.dart:4
error: repository lacks the necessary blob to fall back on 3-way merge.
error: packages/flutter_tools/lib/src/commands/build_bundle.dart: patch does not apply

This problem happens as the patch is created using the latest master, and might fail when applying to other flutter version.
However, it's quite simple to resolve it. The patch contains three parts,
a. build_aot.dart

b.build_bundle.dart

c.aspectd.dart
Not a problem as totally new.

So @xiaobeibeinihao , though the main logic remains, the patch could vary a bit for different flutter versions. For flutter v1.5.4-hotfix2, you can solve it with commands below:
wget https://gist.githubusercontent.com/kangwang1988/e422673f85a2be5a8e43d4b4b745da21/raw/d2f6c4cb3e6a6dbd5ae95d65a25961e0594e9bf1/0001-aspectd-v1.5.4.patch && git apply --3way 0001-aspectd-v1.5.4.patch

It will work as expected.

1、我用你给的patch已经，能执行成功，不会报错。但是我通过正常的编译给的demo，并没有看到print打印KWLM-called 。
2、下载的demo中我用aop.dart编译报错

@xiaobeibeinihao
I think it might be a flutter issue instead of aspectd one. Probably related to flutter/flutter#36326

你好,想请教下是什么原因？
git apply --3way path-for-aspectd-package/0001-aspectd.patch
执行这一步的时候报错
error: packages/flutter_tools/lib/src/commands/build_aot.dart: does not match index
error: packages/flutter_tools/lib/src/commands/build_bundle.dart: does not match index

@newkisky
这个问题现在还有么，有的话麻烦贴一下你的环境(flutter doctor -v)。

This patch issue will remain until flutter/flutter#36738 is resolved and merged into flutter master.
