Flutter – The getter 'title' isn't defined for the class 'TextTheme'

When we run our flutter app we have an error that stop all, and the error don’t say us where it comes from :

Error: The getter 'title' isn't defined for the class 'TextTheme'.
vertical_stack_header_dialog.dart:61
- 'TextTheme' is from 'package:flutter/src/material/text_theme.dart' ('../../flutter/packages/flutter/lib/src/material/text_theme.dart').
text_theme.dart:1
Try correcting the name to the name of an existing getter, or defining a getter or field named 'title'.style: Theme.of(context).textTheme.title,

    1. Make sure you have the latest version of Flutter and Dart SDK installed.
    2. Check if you have imported the necessary packages correctly, especially the ‘material.dart’ package.
    3. Verify that you are using the correct syntax when accessing the ‘title’ getter from the ‘TextTheme’ class. Double-check the spelling and capitalization.
    4. If the issue persists, try running ‘flutter clean’ to clear any cached build artifacts and then rebuild your app.
    5. If none of the above steps work, consider checking for any updates or bug fixes related to the package or library you are using that may address this issue.

    Please note that without seeing the specific code causing the error, it is difficult to provide an exact solution.

    The title field on TextTheme is removed in version 2.2. The replacement for it is headline6.

    You need to replace

    Theme.of(context).textTheme.title

    with

    Theme.of(context).textTheme.headline6

    This is the full list of the old and new APIs:

    OLD         NEW

display4    headline1
display3    headline2
display2    headline3
display1    headline4
headline    headline5
title       headline6
subhead     subtitle1
body2       bodyText1
body1       bodyText2
subtitle    subtitle2
