Flutter WebとFirebase組み合わせたtodowebapppを動かす

https://github.com/theindianappguy/todowebappp を動かす

`flutter packages pub global activate webdev

すると  ``` Warning: Pub installs executables into $HOME/.pub-cache/bin, which is not on your path. You can fix that by adding this to your shell's config file (.bashrc, .bash_profile, etc.):

export PATH="$PATH":"$HOME/.pub-cache/bin"

ってでるがもうzshがMacのデフォルトだよな。なので`~/.zshrc`にいれる。

Dartがないとおこられるｗ

ここいい。

`~/.zshrc`

僕の環境はここだな。

export PATH="$PATH":"$HOME/Sources/dart/flutter/bin/cache/dart-sdk/bin"

The Flutter SDK is not available.って・・・

flutter_web: any flutter_web_ui: any

がなぜない？？

FacebookでSwiftUI

SwiftUIでFacebookログインを。

ほとんどFacebookボタンをそのまま置く感じなので、メソッドをつかうしかない。

メソッドはこれ参考になると思った

中国のWeb（https://stackoom.com/question/3v2sS/使用SwiftUI添加Google登录）に古いコードがあってそれを見た

struct SocialLogin: UIViewRepresentable {
    private let premission = ["public_profile", "email"]
    func makeUIView(context: UIViewRepresentableContext<SocialLogin>) -> UIView {
        return UIView()
    }

    func updateUIView(_ uiView: UIView, context: UIViewRepresentableContext<SocialLogin>) {
    }

    func attemptLoginFb(completion: @escaping (_ result: LoginManagerLoginResult?, _ error: Error?) -> Void) {
        let fbLoginManager: LoginManager = LoginManager()
        fbLoginManager.logOut()
        fbLoginManager.logIn(permissions: premission, from: UIApplication.shared.windows.last?.rootViewController) {
            (result, error) -> Void in completion(result, error)
        }
    }
}

これ作って、

    func FacebookLogin() {
        SocialLogin().attemptLoginFb(completion: { result, error in
        })
    }

こんな感じで呼べた。

Facebookぼたんはこう？

 Button(action: self.logginFb, label: {
                            Image("ic_facebook").foregroundColor(Color.white).frame(width: 20, height: 20)
                        })
