radarlabs / flutter-radar Goto Github PK

Hello There.

As of now, most of the packages/plugin has been migrated to null-safety, and most of the projects use null safety.
Can you guys please migrate to null safety?
I would be happy to work on PR

Thanks
Jigar

Edit. 1
I see there is PR available to merge for null safety.

Any ETA when you guys can merge it

We are currently on the Team Plan and our project name is TD God-View. We integrated the flutter plugin for our product which is a Logistics App.

We have observed some inconsistency in the behaviour of the plugin which we would like to clarify for trips.

1. When we started a trip we noticed the trip did not have the userId field set even though we could see from the logs that we were setting this value
2. Trip was not updated even after calling start trip, we could not see the trip on the radar dashboard. 
3. At some point, after recalling the start trip function pertaining to our use case, we would get the results on radar sometimes in a perfect manner and sometimes we get it inconsistently.

Our implementation
We initialised the plugin on the main method, which was verified because the plugin logged the radar initialise method on the console.
await Radar.initialize(environment['RADAR_PUBLISHABLE_KEY']!);

The plugin logged this: 

I/RadarLogger(21315): :round_pushpin:️ Radar initialized

After initialising the plugin we set the user ID and the user description immediately after the user logged in following the documentation procedure which states that the function is meant to be called only once. And we also verified the plugin stored the data by calling the getUserId function on the plugin.

static Future<void> initRadar(BuildContext context) async{

 /// [TdUser] details
 String userId = context.read<LoginProvider>().currentUser!.id!;
 String displayName = context.read<LoginProvider>().currentUser!.displayName;

 /// [logger]
 log('');
 log('---------------- RADAR INITIALIZED ----------------');
 log('::::: UserId: $userId :::::');
 log('::::: Display Name: $displayName :::::');
 log('');

 /// Setting user's Description
 await Radar.setUserId(userId);
 await Radar.setDescription(displayName);
 await Radar.startTracking('continuous');
 log('Radar tracking');
}

This was logged immediately this method was called:

[log] ---------------- RADAR INITIALIZED ----------------
[log] ::::: UserId: Eds4G5HD2AypMeBPD :::::
[log] ::::: Display Name: Babalola Gbogo :::::

This was logged after a little while
[log] Radar tracking

Then we proceeded to starting a trip in which sometimes it won’t start and sometimes it will.

static Future<void> startTrip({
 required BuildContext context,
}) async {
 final Stop _firstStop = context
   .read<TripProvider>()
   .stops!
   .where((_stop) => _stop.position == 1)
   .toList()
   .first;
 final String externalId =
   '${_firstStop.deliveryTripId}_${_firstStop.stopId}';
 final outlet = await _getRetailOutlet(
  context,
  _firstStop,
 );

 /// [logger]
 log('');
 log('---------------- START TRIP ----------------');
 log('::::: First Stop: ${_firstStop.retailOutletName} :::::');
 log('::::: Outlet Type: ${outletMapper(
  outlet: outlet!.outletType,
 )} :::::');
 log('');

 /// Starting trip with radar
 await _startRadarTrip(
  externalId: externalId,
  outletType: outletMapper(
   outlet: outlet.outletType,
  ),
  outletId: outlet.retailOutletId!,
 );
  log('Trip Started');
}

We verified that it called these methods using the log output

[log] ---------------- START TRIP ----------------
[log] ::::: First Stop: Liquid metal :::::
[log] ::::: Outlet Type: large-super-market :::::

And then after a little delay this got logged
[log] Trip Started

Any plans on a Flutter SDK update regarding the geofencing capabilities already present in the Android/iOS SDKs ? The plugin itself seems amazing for geofencing (my particular use case) but, from what I could see in the official documentation, background tracking regarding geofencing is only present on Android and iOS. There could be fixes around this problem with events but there is also no documentation about those in the Flutter SDK docs. Is this going to be a feature or is it on hold/not planned ?

I have a problem with Radar.onEvents(), is never called :

Radar.initialize("prj_test_pk_*");
Radar.setUserId(mUserId);
Radar.startTracking('responsive');
Radar.onEvents((result) {
    print("RADAR GEOFENCE DETECTED EVENTS");
    print(result);
});

On my IDE logs I've :

But my print on the onEvents listener not show.

What have I done wrong ?

Thanks.

New Flutter projects uses Kotlin for Android and Swift for iOS by default, but in Radar's Flutter plugin docs (https://radar.com/documentation/sdk/flutter) the example is still in Java & Objective C. Since most Flutter devs are like me, who have very limited understanding of native platform, it would be very helpful to include steps to install Radar in Kotlin/Swift.

I also noticed that in my Flutter project, the MainApplication.java file is missing. No equivalent file in Kotlin either. I have no idea where to put the initialization code for Radar.

Am I missing anything?

I have been facing an issue related to working of radar in release mode. While in debug mode the library is working fine with no errors, I think it is being caused due to obfuscation due to which R8 is removing the native code/methods [https://github.com/dart-lang/sdk/blob/master/runtime/docs/compiler/aot/entry_point_pragma.md]. I tried adding @pragma("vm:entry-point") to the flutter_radar.dart but it didn't solve the issue. This same issue is reproducible in the radar example code. Help from the team would be great.

Im not sure it will help in explanation of this issue or debugging as this issue is appearing in stock radar example too. But I have included proguard-rules in my personal project as its an requirement by flutter_local_notifcation package:
proguard-rules.pro

## Gson rules
# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default, so configure it to keep all of it.
#-keepattributes InnerClasses
-keepattributes Signature

# For using GSON @Expose annotation
-keepattributes *Annotation*

# Gson specific classes
-dontwarn sun.misc.**
#-keep class com.google.gson.stream.** { *; }

# Prevent proguard from stripping interface information from TypeAdapter, TypeAdapterFactory,
# JsonSerializer, JsonDeserializer instances (so they can be used in @JsonAdapter)
-keep class * extends com.google.gson.TypeAdapter
-keep class * implements com.google.gson.TypeAdapterFactory
-keep class * implements com.google.gson.JsonSerializer
-keep class * implements com.google.gson.JsonDeserializer

# Prevent R8 from leaving Data object members always null
-keepclassmembers,allowobfuscation class * {
  @com.google.gson.annotations.SerializedName <fields>;
}

# Retain generic signatures of TypeToken and its subclasses with R8 version 3.0 and higher.
-keep,allowobfuscation,allowshrinking class com.google.gson.reflect.TypeToken
-keep,allowobfuscation,allowshrinking class * extends com.google.gson.reflect.TypeToken

Edit: adding @pragma("vm:entry-point") before class Radar make the error E/flutter ( 6472): [ERROR:flutter/shell/common/shell.cc(117)] Dart Error: Dart_LookupLibrary: library 'package:flutter_radar/flutter_radar.dart' not found. go away.

@pragma("vm:entry-point")
class Radar {
  static const MethodChannel _channel = const MethodChannel('flutter_radar');

But the library still doesn't works.
