iOS Flutter App Immediately Opens House Display After Reinstall

Resolution:
To resolve this, I added logic to clear the Keychain when the app is put in for the primary time after being reinstalled. Right here’s the up to date AppDelegate.swift file:

import Flutter
import UIKit
import Safety

@major
@objc class AppDelegate: FlutterAppDelegate {

    func clearKeychainIfReinstalled() {
        let defaults = UserDefaults.commonplace
        let alreadyInstalled = defaults.bool(forKey: "has_installed")

        if !alreadyInstalled {
            clearKeychain()
            defaults.set(true, forKey: "has_installed")
            defaults.synchronize()
        }
    }

    func clearKeychain() {
        let secItemClasses = [
            kSecClassGenericPassword,
            kSecClassInternetPassword,
            kSecClassCertificate,
            kSecClassKey,
            kSecClassIdentity
        ]
        for itemClass in secItemClasses {
            let question = [kSecClass: itemClass]
            SecItemDelete(question as CFDictionary)
        }
    }

    override func software(
        _ software: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        clearKeychainIfReinstalled()
        GeneratedPluginRegistrant.register(with: self)
        return tremendous.software(software, didFinishLaunchingWithOptions: launchOptions)
    }
}

Clarification:

1. Persistent Set up Examine: I used UserDefaults to test if the app has been beforehand put in.
2. Clear Keychain: If the app is being put in for the primary time after a reinstall, the clearKeychain operate known as, which deletes all Keychain gadgets.
3. Keychain Courses: The clearKeychain operate iterates over varied Keychain courses (kSecClassGenericPassword, kSecClassInternetPassword, and so on.) and removes all saved gadgets.

End result:
This ensures that delicate information is cleared upon reinstallation, and the app begins contemporary, taking the person to the login display screen as a substitute of instantly navigating to the house display screen.
