在 flutter 中设置模拟器时遇到问题

Question

我有以下问题......

Error: Variables must be declared using the keywords 'const', 'final', 'var' or a type name.
Try adding the name of the type of the variable or the keyword 'var'.
   int _counter = 0;dsggfsgfh;
                    ^^^^^^^^^
Target kernel_snapshot failed: Exception


FAILURE: Build failed with an exception.

我是 Flutter 的初学者。我怎么解决这个问题？

Answer 1

你可以有这样的东西：

int x = 1;
var y;
double myDouble = 1.0;
