prefer_function_declarations_over_variables
Use a function declaration to bind a function to a name.
Details
#From Effective Dart:
DO use a function declaration to bind a function to a name.
As Dart allows local function declarations, it is a good practice to use them in the place of function literals.
BAD:
dart
void main() {
var localFunction = () {
...
};
}
GOOD:
dart
void main() {
localFunction() {
...
}
}
