Save recursively

[yulingtianxia]

1. Support save objects recursively.
2. Fix encoding for Add and Remove operations.
3. Fix some exceptions.
4. Support batch request and handle response.

There are a lot of things to do:

1. Check dirty objects and unsaved changes.
2. Reconstruction Add, Remove, AddRelation, RemoveRelation ... Array operations should be incremental.
3. Complete features in ACL.

Great work.

It looks like a large amount of changes. I will have to review them and run some tests, but happy to merge this branch for now,

Hi,
I tried running this version and I have the following errors.
It's calling Sebast, I do not remember who made the change, but had suggested to leave SharedPreference with default.

@RodrigoSMarques Have you ever tried the previous version? Perhaps it's a data issue.
It throws exception on calling openDatabase:

@RodrigoSMarques Hi,
Did you solve the issue of
"[VERBOSE-2:ui_dart_state.cc(148)] Unhandled Exception: NoSuchMethodError: The getter 'length' was called on null.

How did you solve it? is that some internal function name changed so makes this error?

When I use VSCode to track, I can reach where @yulingtianxia point out. but VSCode cannot see the local instance data, Android-Studio can do it, but I don't want to install such a huge thing.........

I had figure out why this issue happened.
verison 1.0.22 need masterKey while do Parse().initialize().
When those functions don't need masterKey permission, please don't ask for it.

[RodrigoSMarques]

HI @zenz
Use await in Parse().initialize.
It was one of the changes that occurred in version 22

await Parse().initialize("xxxxxxxxxx",
      "xxxxxxxxxxxxxx",
      autoSendSessionId: true,
      liveQueryUrl: "xxxxxxxxxxxxxx");
