                  icon: Icon(snapshot.data ? Icons.visibility : Icons.visibility_off),

您必须使用“行小部件的属性”来实现所需的输出。

TextFormField(
            decoration: InputDecoration(
              labelText: Strings.AuthPage.PASSWORD,
              hasFloatingPlaceholder: true,
              suffixIcon: Row(
                mainAxisAlignment: MainAxisAlignment.spaceBetween, // added line
                mainAxisSize: MainAxisSize.min, // added line
                children: <Widget>[
                  IconButton(
                    icon: Icon(Icons.clear),
                  ),
                  IconButton(
                    icon: Icon(snapshot.data
                        ? Icons.visibility
                        : Icons.visibility_off),
                    onPressed: _authBloc.switchObscureTextMode,
                  ),
                ],
              ),
            ),
            controller: passwordController,
            obscureText: snapshot.data,
          ),
