I got this error while running the app :-

/D:/flutter/packages/flutter/lib/src/material/bottom_navigation_bar_theme.dart:5:8: Error: Dart library 'dart:ui' is not available on this platform. import 'dart:ui' show lerpDouble;

1. Can you post your response to this command?

   flutter doctor —verbose

2. Can you confirm you are opening correct folder. You should open houzi-1.x.x folder from houzi-flutter-app. Please post screenshot of the project you’ve opened.

3. Flutter 3.0.4 is more than one year old. You should really update your flutter.

1- flutter doctor --verbose

PS C:\Users\User\Desktop\AqaratPlus\houzi-1.1.5_1> flutter doctor -verbose

2- here is a screenshot (https://imgtr.ee/i/oAYhQ) 3- i'm using flutter 3.0.4 based on what i have seen in support section in (themeforest)

From your screenshot, it doesn't seem to be detecting it as flutter project. Once it detects it as flutter project, the folder logo beside houzi-1.1.5_1 will change to flutter logo. Have you installed flutter plugin in Android Studio?

Also it says it isn't detecting java, have you downloaded java and set its environmental variable ie JAVA_HOME etc?

Can you update to latest version 3.7.x

I'm using IntelliJ IDEA and updated flutter & dart as following :-

C:\Users\User>dart --version
Dart SDK version: 2.19.4 (stable) (Tue Mar 7 09:58:46 2023 +0000) on "windows_x64"

C:\Users\User>flutter doctor
