Question

'线程1：EXC_BAD_ACCESS（代码= 1，地址= 0x0）'在AppDelegate.swift中的这一行“GeneratePluginRegistrant.register（with：self）”中GeneratePluginRegistrant.m从这一行

[PathProviderPlugin registerWithRegistrar:[registry registrarForPlugin:@"PathProviderPlugin"]];

AppDelegate.swift

import Flutter
import Firebase


@main
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    FirebaseApp.configure()
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

我认为你不应该将自己（AppDelegate）注册为插件注册，请尝试这个：

import UIKit
import Flutter
import FlutterPluginRegistrant

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  lazy var flutterEngine = FlutterEngine(name: "Flutter Engine")

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