如何在flutter应用中点击后缀图标时，逐一显示密码和确认密码？

bool _obscurePassword = true;
bool _obscureConfirmPassword = true;

TextFormField(
  obscureText: _obscurePassword,
  decoration: InputDecoration(
    labelText: 'Password',
    suffixIcon: IconButton(
      icon: Icon(_obscurePassword ? Icons.visibility : Icons.visibility_off),
      onPressed: () {
        setState(() {
          _obscurePassword = !_obscurePassword;
        });
      },
    ),
  ),
),

TextFormField(
  obscureText: _obscureConfirmPassword,
  decoration: InputDecoration(
    labelText: 'Confirm Password',
    suffixIcon: IconButton(
      icon: Icon(_obscureConfirmPassword ? Icons.visibility : Icons.visibility_off),
      onPressed: () {
        setState(() {
          _obscureConfirmPassword = !_obscureConfirmPassword;
        });
      },
    ),
  ),
),
