Menu
I'm currently creating an simple application with flutter(Dart). And when i want to create the AppBar widget, i cant give it names with '$'. Because, same like Kotlin..Dart is using '$' for summoning an identifier.
Any solution?
var _appbar = AppBar(
title: Text("How I Made $100"), //$ is the error
);

String interpolation is the process of inserting variable values into placeholders in a string literal. To concatenate strings in Dart, we can utilize string interpolation. We use the ＄{} symbol to implement string interpolation in your code.
The dollar sign is a special character, so if you want it to be ignored you have to escape it with a \.
For example:
void main() {
print("This string contains a dollar \$ign");
}
