SoftAssertions

Utility class to make assertions that should not hard-crash the app but instead be handled by the Catalyst app JSExceptionHandler. See the javadoc on that class for more information about our opinion on when these assertions should be used as opposed to assertions that might throw AssertionError Throwables that will cause the app to hard crash.

Functions

assertCondition

@JvmStatic

fun assertCondition(condition: Boolean, message: String)

Asserts the given condition, throwing an AssertionException if the condition doesn't hold. This logs an assertion with ReactSoftExceptionLogger, which decides whether or not to actually throw.

assertNotNull

@JvmStatic

fun <T> assertNotNull(instance: T?): T?

Asserts that the given object isn't null, throwing an AssertionException if it was. This logs an assertion with ReactSoftExceptionLogger, which decides whether or not to actually throw.

assertUnreachable

@JvmStatic

fun assertUnreachable(message: String)

Throw AssertionException with a given message. Use this method surrounded with if block with assert condition in case you plan to do string concatenation to produce the message. This logs an assertion with ReactSoftExceptionLogger, which decides whether or not to actually throw.
