Using Config File generates Exception after updating to 3.7.0: MissingPluginException no implementation found for method

[Smibser]

Since I updated flutter_segment to 3.7.0 I get the following exception on app start when I call Segment.config(...)

The last working version is 3.3.0

@Smibser Please run

flutter pub get
then
Run the project

[danielgomezrico]

if what @ariefwijaya dont work, can you share a working example that reproduce the issue? I am not able to reproduce it

[limonadev]

The problem appears when there are configuration keys in the Info.plist file (the deprecated ones). The PR #94 added a boolean wasSetupFromFile that is causing the problem when there are two setups, from Info.plist and from dart method Segment.config. The solution is to simply remove the configuration keys from Info.plist.

[danielgomezrico]

We should remove the deprecated configs 🤔

[limonadev]

We probably should add that to the README, and also remove the boolean wasSetupFromFile as the configuration file is no longer needed/supported.

[danielgomezrico]

Mm I see that theres a method that handles this:

flutter-segment/ios/Classes/FlutterSegmentPlugin.m

Lines 347 to 364 in 16f9fbe

	+ (SEGAnalyticsConfiguration*)createConfigFromFile {
	NSString *path = [[NSBundle mainBundle] pathForResource: @"Info" ofType: @"plist"];
	NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile: path];
	NSString *writeKey = [dict objectForKey: @"com.claimsforce.segment.WRITE_KEY"];
	BOOL trackApplicationLifecycleEvents = [[dict objectForKey: @"com.claimsforce.segment.TRACK_APPLICATION_LIFECYCLE_EVENTS"] boolValue];
	BOOL isAmplitudeIntegrationEnabled = [[dict objectForKey: @"com.claimsforce.segment.ENABLE_AMPLITUDE_INTEGRATION"] boolValue];
	if(!writeKey) {
	return nil;
	}
	SEGAnalyticsConfiguration *configuration = [SEGAnalyticsConfiguration configurationWithWriteKey:writeKey];
	configuration.trackApplicationLifecycleEvents = trackApplicationLifecycleEvents;
	if (isAmplitudeIntegrationEnabled) {
	[configuration use:[SEGAmplitudeIntegrationFactory instance]];
	}
	return configuration;
	}

@Smibser the issue happens on which device? android or iOS?

[danielgomezrico]

This may be related to this issues:

• Confusing Documentation needs to be improved #42
• Installation via Dart Code claimsforce-gmbh/flutter-segment#49

[danielgomezrico]

@limonadev the feature exists for compatibility reasons, its deprecated but it should work, if it is not working... to me we can remove the deprecated code since the warning exists since 2021, feel free to send a contribution :)
