Generate asset.dart At VSCode 's Regex
We can write following code to create Image Widget In Flutter

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

but, It is difficult to prove this code is corrent.
because "assets/images/food_purple_chocolate_dessert.jpg" may be not found .

So, Generate a Code, it mechanically at Regex

like following.

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

and use

return Image.asset(assets.images_food_purple_chocolate_dessert_jpg);

[ps]: In the future, VSCode's Flutter plug-in or will be discovered at compile time, so this is only know-how for now.

(1) List assets image

: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)Creaet assets.dart

./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) Erase "./"

erase "./" at vscode regex

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) Convert into varable

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 "_"

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'
 = ''

Add "Const" and ";"

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

const 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';
