我有一个连续的图像和该图像旁边的文本。我希望该行完全展开，图像作为其大小，然后保持完整区域应由 Container 使用。

这是我的代码片段：

Row(
        children: <Widget>[
          Container(
            margin: EdgeInsets.fromLTRB(10, 50, 10, 8),
            decoration: BoxDecoration(
              color: Colors.white,
              boxShadow: [
                BoxShadow(
                  color: Color.fromARGB(100, 0, 0, 0),
                  blurRadius: 5,
                ),
              ],
            ),
            child: Row(
              mainAxisSize: MainAxisSize.max,
              children: <Widget>[
                Column(children: <Widget>[
                  Image.asset(
                    'assets/card.png',
                    height: 62,
                    width: 62,
                    fit: BoxFit.cover,
                  )
                ]),
                Container(
                  child: Text("Hello world"),
                )
              ],
            ),
          ),
        ],
      ),

我想要这样： Flutter UI

我的计算机上的云功能可以使用 Javascript，但是当我使用 TypeScript 尝试它时，它不会编译为 Javascript。它不会创建 lib/index.js 事件

当我运行 firebase 部署时，它显示以下错误

Error: There was an error reading functions/package.json:\n

firebase deploy --debug 显示以下日志：

我正在尝试使用 facebook 登录 Firebase。

我正在使用 firebaseauth:0.7.0 和 flutter_facebook_login：

这是我的 facebook 登录功能：

  startFacebookLogin() async {
    var facebookLogin = FacebookLogin();
    var result = await facebookLogin
        .logInWithReadPermissions(['email', 'public_profile']);
    FacebookAccessToken myToken = result.accessToken;
    AuthCredential credential =
        FacebookAuthProvider.getCredential(accessToken: myToken.token);
    FirebaseUser firebaseUser =
        await FirebaseAuth.instance.signInWithCredential(credential);
    createProfile(user);
  }

在这里我得到了这个错误：
