#Flutter #Dart #CSS
CSS vs Flutter.
How to embed CSS examples in the text widget.
My success story.
Of course, you can find 15 awesome examples below.
🧵👇 Image
1 #Flutter #Dart #CSS
When I found an example, I thought, why not?
Shadows in CSS has this syntax:
// text-shadow: [horizontal offset] [vertical offset] [blur radius] [color];
// text-shadow: 0 2px 1px #747474,
// rgbo: 0px -4px 10px rgba(255,255,255,0.3);
2 #Flutter #Dart #CSS
Each shadow in the Text widget has 5 lines of code.
Shadow(
color: Color(0xFFFFFFFF),
offset: Offset(1.0, 1.0),
blurRadius: 1.0,
),
It's all good, but I broke my head when I found the example with 26 shadows.
WTF... 🤯🤯🤯

final, const & late in 3+ steps.
🧵👇
1/1
What is the difference between final and const?
A constant variable must be initialized at the time of declaration. It's a compile-time constant. A final variable can be initialized later, but only once when the first time it’s used.
1/2
void main() {
final int x;
const int y = 1;
x = 8; // ok
y = 2; // error: Constant variables can't be assigned a value.
x = 9; // error: The final variable 'a' can only be set once.
}
