Implementing Flutter Icons in the `buildMenuItem()` Widget

Issue

In the Container widget, I have tried implementing many flutter icons and all are working well except for the cell_tower_rounded. This is an icon that is as well supported by icons Null safety.Kindly help why is this cell_tower icon not working while the rest are just ok. My editor underlines it in red and the error is undefined_getter

Container(padding,child,childred[
buildMenuItem(
    text: 'Connection Status',
    icon: Icons.cell_tower_rounded,
    onClicked: () => selectedItem(context, 0),
]),

Solution

Thank you for your contributions, But well, I figured it out and found a fix. The problem was that my Flutter Version was out of date. Most of the latest icons are not easily supported in previous flutter versions. I was using Flutter: 2.8.2 while at the time of release of cell_tower_rounded icon, flutter version was at Flutter: 2.10.2. Incase you are experiencing a unique problem with some widgets, packages or icons, simple run: $ flutter upgrade in your project directory.

You'll probably also need to update your Kotlin Version in the android/build.gradle to the latest one.Find the latest Kotlin version here: Today(as at the time of this post), the latest one is version 1.6.0, so kindly update like this:

buildscript {
    ext.kotlin_version = '1.6.0'
