Function talk = () {

print(msg);
};
return say;
};
main() {
//sample1 for scope--------------------------------------
levelOne();
int i = 999;
for (var i = 0; i < 10; i++) {
print(i);
}
print('i in global scope : ${i}'); //i in global scope : 999
for (i = 0; i < 10; i++) {
print(i);
}
print('i in global scope : ${i}'); //i in global scope : 10
