Class Email sign-in widget with OTP verification, matching the official Crossmint RN SDK email auth flow. 
class CrossmintEmailSignIn extends StatefulWidget
Step 1: email input → calls CrossmintAuthClient.sendEmailOtp. Step 2: 6-char OTP code → calls CrossmintAuthClient.confirmEmailOtp. The state machine lives in CrossmintEmailSignInViewModel, which can be supplied via viewModel for testing or to share state with a custom UI. When omitted, the widget constructs and owns its own view model for the duration of its State lifetime.

Constructors

​
CrossmintEmailSignIn

const CrossmintEmailSignIn({
  super.key,
  required this.auth,
  this.viewModel,
  this.otpTitle,
  this.onAuthenticated,
  this.onError,
})

​
Properties

​
auth

final CrossmintAuthClient auth

​
viewModel

final CrossmintEmailSignInViewModel? viewModel
Optional view model override. When null, the widget constructs a fresh CrossmintEmailSignInViewModel bound to auth and disposes it with the widget. When provided, the widget observes the view model but does not dispose it — the caller owns the lifecycle.

​
otpTitle

final String? otpTitle
Custom title for the OTP verification step. Defaults to 'Check your email'.

​
onAuthenticated

final VoidCallback? onAuthenticated

​
onError

final void Function(Object error)? onError

​
Methods
