const_initialized_with_non_constant_value
Const variables must be initialized with a constant value.
Description
#The analyzer produces this diagnostic when a value that isn't statically known to be a constant is assigned to a variable that's declared to be a const
variable.
Example
#The following code produces this diagnostic because x
isn't declared to be const
:
var x = 0;
const y = x;
Common fixes
#If the value being assigned can be declared to be const
, then change the declaration:
const x = 0;
const y = x;
If the value can't be declared to be const
, then remove the const
modifier from the variable, possibly using final
in its place:
var x = 0;
final y = x;
