VSCode 정규 표현식을 사용하여 assets 작업을위한 asset.dart 생성
하는 방법에 대해 씁니다.

Flutter에서 Assets을 사용하는 경우 문자열로 지정합니다.

return Image.asset("assets/images/food_purple_chocolate_dessert.jpg");

지금까지이 코드에 문제가 있다는 것은 실제로 움직일 때까지
모르겠어요.

그래서 기계적으로,

const images_food_purple_chocolate_dessert_jpg = 'assets/images/food_purple_chocolate_dessert.jpg';

같은 코드를 기계적으로 써주고,

return Image.asset(assets.images_food_purple_chocolate_dessert_jpg);

로 사용하면 실수는 없어집니다.

※ 장래적으로는, VSCode 의 Flutter 의 플러그인~ 컴파일시에 발견해 준다고 생각하므로 지금만의 노하우입니다

(1) Assets 이미지 나열

:myapp kyorohiro$ find ./assets
./assets/
./assets/.DS_Store
./assets/images
./assets/images/food_pizza_slice_fast.jpg
./assets/images/food_dim_sum_squid.jpg
./assets/images/food_chili_cheese_bowls.jpg
./assets/images/flower_orange_calendula_bright_0.jpg
./assets/images/food_pasta_tomato_theme.jpg
./assets/images/food_purple_chocolate_dessert.jpg
:myapp kyorohiro$ 

(2) assets.dart 만들기

./assets/images/food_pizza_slice_fast.jpg
./assets/images/food_dim_sum_squid.jpg
./assets/images/food_chili_cheese_bowls.jpg
./assets/images/flower_orange_calendula_bright_0.jpg
./assets/images/food_pasta_tomato_theme.jpg
./assets/images/food_purple_chocolate_dessert.jpg

(3) "./" 삭제

find: "\.\/" , replace: "" 

assets/images/food_pizza_slice_fast.jpg
assets/images/food_dim_sum_squid.jpg
assets/images/food_chili_cheese_bowls.jpg
assets/images/flower_orange_calendula_bright_0.jpg
assets/images/food_pasta_tomato_theme.jpg
assets/images/food_purple_chocolate_dessert.jpg

(4) 변수처럼 변환

find: "(.*)" , replace: "$1 = '$1'" 

assets/images/food_pizza_slice_fast.jpg = 'assets/images/food_pizza_slice_fast.jpg'
assets/images/food_dim_sum_squid.jpg = 'assets/images/food_dim_sum_squid.jpg'
assets/images/food_chili_cheese_bowls.jpg = 'assets/images/food_chili_cheese_bowls.jpg'
assets/images/flower_orange_calendula_bright_0.jpg = 'assets/images/flower_orange_calendula_bright_0.jpg'
assets/images/food_pasta_tomato_theme.jpg = 'assets/images/food_pasta_tomato_theme.jpg'
assets/images/food_purple_chocolate_dessert.jpg = 'assets/images/food_purple_chocolate_dessert.jpg'
 = ''

(5) "/" and "." into "_"

변수에 사용할 수 없는 문자를 바꿉니다.

find: "(.*)/(.*) = (.*)" , replace: "$1_$2 = $3"
find: "(.*)\.(.*) = (.*)" , replace: "const $1;"  

assets_images_food_pizza_slice_fast_jpg = 'assets/images/food_pizza_slice_fast.jpg'
assets_images_food_dim_sum_squid_jpg = 'assets/images/food_dim_sum_squid.jpg'
assets_images_food_chili_cheese_bowls_jpg = 'assets/images/food_chili_cheese_bowls.jpg'
assets_images_flower_orange_calendula_bright_0_jpg = 'assets/images/flower_orange_calendula_bright_0.jpg'
assets_images_food_pasta_tomato_theme_jpg = 'assets/images/food_pasta_tomato_theme.jpg'
assets_images_food_purple_chocolate_dessert_jpg = 'assets/images/food_purple_chocolate_dessert.jpg'
 = ''

(6) "Const"와 ";"를 부여

find: "^(.*)$" , replace: "const $1;" 

onst assets_images_food_pizza_slice_fast_jpg = 'assets/images/food_pizza_slice_fast.jpg';
const assets_images_food_dim_sum_squid_jpg = 'assets/images/food_dim_sum_squid.jpg';
const assets_images_food_chili_cheese_bowls_jpg = 'assets/images/food_chili_cheese_bowls.jpg';
const assets_images_flower_orange_calendula_bright_0_jpg = 'assets/images/flower_orange_calendula_bright_0.jpg';
const assets_images_food_pasta_tomato_theme_jpg = 'assets/images/food_pasta_tomato_theme.jpg';
const assets_images_food_purple_chocolate_dessert_jpg = 'assets/images/food_purple_chocolate_dessert.jpg';
