flutter_generate_assets
Automatically generate the dart file for pubspec.yaml
The purpose of this library is to help flutter developers automatically generate asset corresponding dart files to help developers release their hands from this meaningless job, and the open source community has a lot of the same functionality.
This library is based on dartlang's build library.

Usage
use source
add dart,pub to $PATH environment.
git clone https://github.com/cherrybiu/flutter_generate_assets.git
cd flutter_generate_assets
pub get
dart bin/resource_generator.dart -s $flutter_project
pub global
install:
pub global activate flutter_generate_assets
use:
sgen
or
sgen -s $flutter_project`
Support options
Use $ sgen -h or $ sgen --help see usage document.
sgen -h
-w, --[no-]watch Continue to monitor changes after execution of orders.
(defaults to on)
-p, --[no-]preview Generate file with preview comments.
(defaults to on)
-o, --output Your resource file path.
If it's a relative path, the relative flutter root directory
(defaults to "lib/const/resource.dart")
-s, --src Flutter project root path
(defaults to ".")
-n, --name The class name for the constant.
(defaults to "R")
-h, --[no-]help Help usage
-d, --[no-]debug debug info
File name
Space, '.' and '-' in the path will be converted to _. @ will be converted to _AT_.
convert filed name example:
images/1.png => IMAGES_PNG
images/hello_world.jpg => IMAGES_HELLO_WORLD_JPG
images/hello-world.jpg => IMAGES_HELLO_WORLD_JPG
Errors will occur in the following situations
images/
main_login.png
main/
login.png
Because the two field names will be exactly the same.
Config file
The location of the configuration file is conventional.
Configuration via commands is not supported.
The specified path is sgen.yaml in the flutter project root directory.
exclude and include rules
The file is yaml format, every element is glob style.
The name of the excluded file is under the exclude node, and the type is a string array. If no rule is included, it means no file is excluded.
The include node is the name of the file that needs to be imported, and the type is a string array. If it does not contain any rules, all file are allowed.
In terms of priority, exclude is higher than include, in other words:
First import the file according to the include nodes, and then exclude the files.
Example
exclude:
- "**/add*.png"
- "**_**"
include:
- "**/a*.png"
- "**/b*"
- "**/c*"
