[Solved] enable the go to next step button, tried setting up state and created new onclick method in the radio button


https://codesandbox.io/s/6zrw7r66rr

I have forked your codesandbox, and edit 4 files. Pretty sure it satisfies all your requirements stated above

VerticalLinearStepper.js: this is where we store our username, password, disabledNext (radioButton) state and handleChange method for setState. Then, we passed down the state to -> Step1.js -> AsyncValidationForm.js.

class VerticalLinearStepper extends React.Component {
  state = {
    activeStep: 0,
    //we set our state in this parent
    disabledNext: true,
    username: "",
    password: ""
  };

  steps = {
    "Select campaign settings": Step1,
    "Create an ad group": Step2,
    "Create an ad": Step3
  };

  //setState for disabledNext
  handleChangeDisabledNext = value => {
    this.setState({ disabledNext: value });
  };
  //setState for username, password
  handleChange = (name, value) => {
    this.setState({ [name]: value });
  };

  stepsCount = () => Object.values(this.steps).length;

  canGoBack = () => this.state.activeStep > 0;
  canGoForward = () => this.state.activeStep < this.stepsCount();

  isFinished = () => this.state.activeStep === this.stepsCount();

  handleBack = () => {
    if (this.canGoBack()) {
      this.setState(prevState => ({ activeStep: prevState.activeStep - 1 }));
    }
  };

  handleNext = () => {
    if (this.canGoForward()) {
      this.setState(prevState => ({ activeStep: prevState.activeStep + 1 }));
    }
  };

  handleReset = () => this.setState({ activeStep: 0 });

  render() {
    const { classes } = this.props;
    const { activeStep } = this.state;

    return (
      <div className={classes.root}>
        <Stepper activeStep={activeStep} orientation="vertical">
          {Object.entries(this.steps).map(([label, CustomStep]) => (
            <Step key={label}>
              <StepLabel>{label}</StepLabel>
              <StepContent>
                <CustomStep
                  canGoBack={this.canGoBack()}
                  canGoForward={this.canGoForward()}
                  onBack={this.handleBack}
                  onNext={this.handleNext}
                  classes={classes}
                  //we pass down the state and its' setState method
                  handleChangeDisabledNext={this.handleChangeDisabledNext}
                  disabledNext={this.state.disabledNext}
                  handleChange={this.handleChange}
                  username={this.state.username}
                  password={this.state.password}
                />
              </StepContent>
            </Step>
          ))}
        </Stepper>

        {this.isFinished() && (
          <Paper square elevation={0} className={classes.resetContainer}>
            <Typography>All steps completed - you&apos;re finished</Typography>
            <Button onClick={this.handleReset} className={classes.button}>
              Reset
            </Button>
          </Paper>
        )}
      </div>
    );
  }
}

In AsyncValidationForm.js, we bind onChange method to track the value and call the setState method and this.props.handleChange for setState in VerticalLinearStepper.js

const renderField = ({
  input,
  label,
  type,
  //checked is for radio, initialValue is for setting the username, password value
  checked,
  initialValue,
  meta: { asyncValidating, touched, error }
}) => {
  return (
    <div>
      <label>{label}</label>
      <div className={asyncValidating ? "async-validating" : ""}>
        <input
          {...input}
          value={initialValue} //add value attr
          checked={checked} //add checked attr
          type={type}
          placeholder={label}
        />
        {touched && error && <span>{error}</span>}
      </div>
    </div>
  );
};

class AsyncValidationForm extends React.Component {
  constructor(props) {
    super(props);
    console.log("AsyncValidationForm ---->");

    this.state = {
      //pass down VerticalLinearStepper.js state if any
      username: this.props.username ? this.props.username : "",
      password: this.props.password ? this.props.password : "",
      //this determines whether any fields is filled or not from VerticalLinearStepper
      pristine:
        this.props.username || this.props.password || !this.props.disabledNext
          ? false
          : true
    };
  }

  passRadioValue = e => {
    this.setState({ pristine: false }, () => {
      this.props.handleChangeDisabledNext(!e.target.checked);
    });
  };

  handleChange = name => event => {
    const value = event.target.value;
    this.setState(
      {
        [name]: value,
        pristine: false
      },
      () => {
        this.props.handleChange(name, value); //setState username, password of VerticalLinearStepper.js
      }
    );
  };

  resetForm = () => {
    this.props.handleChangeDisabledNext(true); //setState disabledNext of VerticalLinearStepper.js
    this.setState(
      {
        username: "",
        password: "",
        pristine: true
      },
      () => {
        this.props.handleChange("username", "");
        this.props.handleChange("password", "");
      }
    );

    this.props.reset();
  };

  // this.setState({ disabled: !this.state.disabled });

  render() {
    const { handleSubmit, pristine, reset, submitting } = this.props;

    return (
      <form onSubmit={handleSubmit}>
        <Field
          name="username"
          type="text"
          component={renderField}
          label="Username"
          initialValue={this.state.username}
          onChange={this.handleChange("username")}
        />
        <Field
          name="password"
          type="password"
          component={renderField}
          label="Password"
          initialValue={this.state.password}
          onChange={this.handleChange("password")}
        />

        <label>
          <Field
            name="sex"
            component={renderField}
            type="radio"
            value="male"
            checked={!this.props.disabledNext}
            onChange={this.passRadioValue}
          />{" "}
          Male
        </label>

        <div>
          <button type="submit" disabled={submitting}>
            Sign Up
          </button>
          <button
            type="button"
            disabled={(pristine || submitting) && this.state.pristine} //add state.pristine checking
            onClick={this.resetForm}
          >
            Clear Values
          </button>
        </div>
      </form>
    );
  }
}

Then, in StepTemplate.js Add disabledNext, checkDisabledNext props. checkDisabledNext to determine whether the Next Button will have conditional checking or not. disabledNext is the disabled value.

const StepTemplate = ({
  classes,
  canGoBack,
  canGoForward,
  onBack,
  onNext,
  text,
  children,
  //we pass down these 2 values
  disabledNext,
  checkDisabledNext
}) => (
  <Fragment>
    <Typography>{text}</Typography>

    <div className={classes.actionsContainer}>
      <div>
        {children}

        <Button
          disabled={!canGoBack}
          onClick={onBack}
          className={classes.button}
        >
          Back
        </Button>
        <Button
          variant="contained"
          color="primary"
          onClick={onNext}
          className={classes.button}
          //determine whether we should check button disabled or not
          disabled={checkDisabledNext ? disabledNext : false}
        >
          {canGoBack ? "Next" : "go to next step"}
        </Button>
      </div>
    </div>
  </Fragment>
);

This is Step1.js, here we just pass props to StepTemplate and AsyncValidationForm:

const Step = props => (
  <StepTemplate

Update VerticalLinearStepper.js, then we dont need Step1.js file anymore, since we write the content of Step1.js in this file:

solved enable the go to next step button, tried setting up state and created new onclick method in the radio button
