即使操作成功执行后，React-Native中的Redux状态为null

Question

Redux state is null, even after execution of the action being successful!

My app has a login button which when clicked, it triggers an action:

src / Screen / Member / SignIn / index.js, line 40: this.props.tryLogin (email, password)

In the action file:

/src/actions/userActions.js

The action tryLogin () is executed successfully, and there is the normal dispatch:

const action = userLoginSuccess (res);
dispatch (action);

The execution succeeds, and the app redirects to app home:

/src/Screen/Public/Home/index.js

The problem is right here, when I try to read the redux state: in the file:

/src/Component/Menu/Left/index.js, line: 206

mapStateToProps () ,

The state is null , even with the action userLoginSuccess () having been successfully executed !!!

My repository to test: https://github.com/tmacedo2014/EstudoReactNative

Data to use in test login: email: tiberius.macedo@gmail.com pass: 123456

Answer 1

You have a typo in your action type. In actions/userActions.js you named the action constant USER_LOGIN_SUCESS but in reducers/userReducer.js you import USER_LOGIN_SUCCESS .

If you fix this typo, everything else looked like it was hooked up correctly.
