Installation

1. Activate the package globally via Dart's pub tool:

dart pub global activate flutter_loc

Once activated, you can use the flutter_loc command directly in your terminal.

Usage

1. Generate Localization Files

Extract hard-coded strings in your working directory with a single command:

flutter_loc extract -d /your/working/directory

This will extract all of the caught hard-coded strings in all of the dart files in that directory, and dump them into a special flutter_loc.txt file.

2. Work with the flutter_loc.txt file

You will find a txt file generated similar to this:

##PATH-START{file://D:\path\to\test.dart}##
#----------#
##MATCH-LINE{28}##
(17) 'Hard-coded string 1' ===> "" !;;!


##MATCH-LINE{126}##
(29) "Hard-coded string 2 with double quotes" ===> "" !;;!


##MATCH-LINE{126}##
(29) "some line with two strings, this is the first" ===> "" !;;!
(65) "And this is the second" ===> "" !;;!


##MATCH-LINE{152}##
(28) """ Triple-quotes
Multiline
hard-coded strings
""" ===> "" !;;!


##MATCH-LINE{154}##
(32) "Some string with $variable" ===> "" !;;!


##MATCH-LINE{154}##
(32) "Some other with ${encodedvariable? 'and inner quotes': 'other inner quotes'}" ===> "" !;;!
#----------#
##PATH-END##

All you have to do? Give each hard-coded string a key. Easy!

##PATH-START{file://D:\path\to\test.dart}##
#----------#
##MATCH-LINE{28}##
(17) 'Hard-coded string 1' ===> "str1_key" !;;!


##MATCH-LINE{126}##
(29) "some line with two strings, this is the first" ===> "str3_key" !;;!
(65) "And this is the second" ===> "str4_key" !;;!


##MATCH-LINE{152}##
(28) """ Triple-quotes
Multiline
hard-coded strings
""" ===> "long_text_key" !;;!


##MATCH-LINE{154}##
(32) "Some string with $variable" ===> "key_of_var" !;;!

...
#----------#
##PATH-END##

3. Replace the cought hard-coded strings with the newly created keys, and generate a JSON file with them.

Run the replace command to update your files and create JSON files for supported languages:

flutter_loc replace -p path/to/flutter_loc.txt -l en,ar,es

And this would conveniently:

1. Replace the text in the original file with your set key (It will ignore the ones you left empty in the flutter_loc file).
2. Create JSON files for the supported languages you specified (using the -l argument, e.g. -l en,ar,es).
3. Populate these files with a JSON map of the keys you supplied, and the values (the original text if it's the main language, an empty string if not).
4. And that's it! Get your original language file and translate it to as many as you want!

{
  "str1_key": "Hard-coded string 1",
  "long_text_key": "Triple-quotes\nMultiline\nhard-coded strings",
  "key_of_var": "Some string with variable"
}
