Initialize native SDKs before JS

[krystofwoldrich]

Available in https://github.com/getsentry/sentry-react-native/releases/tag/6.7.0-alpha.0

Create sentry.options.json in the React Native project root and set options the same as you currently have in Sentry.init in JS.

{
    "dsn": "https://[email protected]/value",
}

Initialize Sentry on the native layers by newly provided native methods.

import io.sentry.react.RNSentrySDK

class MainApplication : Application(), ReactApplication {
    override fun onCreate() {
        super.onCreate()
        RNSentrySDK.init(this)
    }
}

#import <RNSentry/RNSentry.h>

@implementation AppDelegate
- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [RNSentrySDK start];
    return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
@end

@krystofwoldrich customer is asking:

do you have any timeline/estimate around when this issue could be fixed?

[krystofwoldrich]

@realkosty We don't have a timeline yet. But it's possible to capture the startup crashes when initializing the native SDKs manually. The How to set up for start up crashes at the moment part of the issue.

@krystofwoldrich we should also update at least one sample app to use this IMO :) (may be part of the e2e test task above, so I didn't add an item, please go ahead if you want to track it separately)
