hi , It ok to do this in a single launch ? or do we have to use separate launch for repeat on life cylce ?
lifecycleScope.launch {

lifecycle.repeatOnLifecycle(Lifecycle.State.STARTED) {
loginAuthorizationViewModel.onLoginSuccessful.collect {
startActivity(HomeActivity.getDefaultIntent(this@LoginActivity))
finish()
}
}

lifecycle.repeatOnLifecycle(Lifecycle.State.STARTED) {
loginInputValidationViewModel.onPasswordInvalid.collect {
enableViews(true)
et_password.error = it
}
}

lifecycle.repeatOnLifecycle(Lifecycle.State.STARTED) {
loginAuthorizationViewModel.onLoginFailure.collect {
enableViews(true)
showMessage(it.toString())
}
}

lifecycle.repeatOnLifecycle(Lifecycle.State.STARTED) {
loginInputValidationViewModel.onUserNameInvalid.collect {
enableViews(true)
tv_user_name.error = it
}
}

lifecycle.repeatOnLifecycle(Lifecycle.State.STARTED) {
loginInputValidationViewModel.onValidationSuccessful.collect {
loginAuthorizationViewModel.requestLogin(
userName = it.first,
password = it.second
)
}
}

I think under the hood repeatOnLifecycle launch its own coroutines

@Javier my trial shows it doesn't work. I feel there are better ways to do this, however i just don't know how.

[althaf]

we have to use different launch

[agrosner]

Separate launches within repeat on lifecycle

[agrosner]

Call launch on all inner suspends

Inside repeatOnLifecycle, for every flow you can do flow.onEach { do something }.launchIn(this) (where this is the coroutine scope).
It is equivalent to launch { flow.collect { do something } }
