Edit the plugin's libs/models/State.dart: Comment-out line 49. I suspect it will fail again at line 59. It would seem that iOS 10 is failing to render iOS YES / NO (which are 1/0)

Will try going through the state source and comment out as suggested to see if it can get by.

christocracy · 2019-08-25T02:38:09Z

in lib/background_geolocation.dart, I'm interested in seeing the raw data provided by iOS before State is instantiated.

Put this in there: here it's a bool. I'm guessing on your device it's an int (probably 0).

static Future<State> ready(Config config) async {
    Map state = await _methodChannel.invokeMethod('ready', config.toMap());
+   print("*************** BEFORE new State: disableElasticity: ${state['disableElasticity']}");
    return new State(state);
}

flutter: *************** BEFORE new State: disableElasticity: false

Also, see if you can reproduce this on iOS 12 sim (I doubt you will).

leetworx · 2019-08-25T15:31:33Z

Hey Chris,

Looks like your suspicions are correct - here's the output from the snippet:

flutter: *************** BEFORE new State: disableElasticity: 0

And yes, running this on an iPhone XR (12.2) in the simulator (or my Android device...), no problem.

Wondering if this is a case of finding a new lower bound on system requirements for the plugin or do you see it as something that is resolvable in the near term?

christocracy · 2019-08-25T15:35:44Z

It can be supported by doing something like this, checking the .runTimeType to turn int to bool.

leetworx · 2019-08-26T01:57:29Z

This seems to resolve the runtime type issue - looks like I can't create a PR directly, but here's a patch file (.txt) in case you find it helpful. BTW - great plugin, really enjoying getting to know my way around.

0001-fix-runtime-type-issue-int-bool-found-on-older-physi.patch.txt

christocracy · 2019-08-26T01:59:34Z

Of course a pr can be made directly, but I’ve already provided int checks for all bool params. Will be pushed tomorrow.

leetworx · 2019-08-26T02:07:31Z

I mean no write for branch creation (I looked) - suppose I could fork. Regardless, thanks for the update.

christocracy · 2019-08-26T02:09:28Z

Yes, that’s how github PR workflow generally works. You fork then submit PR back.

christocracy · 2019-08-26T16:10:00Z

Try installing from master. See README Installing from Git

leetworx · 2019-08-26T16:45:25Z

Verified - thanks!

leetworx · 2019-08-26T17:49:07Z

FYI, just noticed an additional runtime type buried in the logs - line 138: e.g

        enableTimestampMeta: (data['enableTimestampMeta'].runtimeType == int)
    	? (data['enableTimestampMeta'] != 0)
    	: data['enableTimestampMeta'],

Oddly, it didn't appear to be fatal when I was running on validation (but then I'm battling an unrelated cloud firestore issue - so it may have gotten buried.

christocracy · 2019-08-27T13:45:44Z

Re-install from master. I've created some helper methods _ensureBool, _ensureInt and _ensureDouble to help manage things.

christocracy · 2019-08-28T14:46:27Z

Let me know if current master is all good for you.

leetworx · 2019-08-31T01:50:33Z

Check - looks great, thanks!

leetworx · 2020-03-02T02:53:02Z

Just FYI, pulled out my old iPhone 5c for testing a build and this cropped up again, so you may want to reopen.

Looks like the state fields for 'disableAutoSyncOnCellular' and 'encrypt' require the _ensureBool wrapper.

christocracy · 2020-03-02T12:34:04Z

Damn. I’m on vacation until next week.

Hey Chris - put up a small PR in case that helps.
Verified this works as expected on the iPhone 5c
