How many lines does your Flutter project have?

flutter-project-line.md

• Open terminal and go to your project's lib folder. After that run the command below.
• find . -name '*.dart' ! -name '*.g.dart' ! -name '*.freezed.dart' ! -name '*.gr.dart' ! -name '*.gen.dart' | xargs wc -l

Thanks @AcetylsalicylicAcid for excluding generated files.

how to get count with out library code

don't forget that you may have a lot of generated files in dart

Hi @karmazinkd, I'm updated the command. Thanks to @AcetylsalicylicAcid 🙌

sort by numbers of lines of code
find . -name '*.dart' ! -name '*.g.dart' ! -name '*.freezed.dart' ! -name '*.gr.dart' ! -name '*.gen.dart' | xargs wc -l | sort -n

for anyone who wonders how to make this in Windows 10 PowerShell.

$totalLines = 0
Get-ChildItem -Recurse -Filter "*.dart" | Where-Object {!($_.Name -like "*.g.dart" -or $_.Name -like "*.freezed.dart" -or $_.Name -like "*.gr.dart" -or $_.Name -like "*.gen.dart")} | ForEach-Object {
    $lineCount = (Get-Content $_.FullName | Measure-Object -Line).Lines
    $totalLines += $lineCount
    Write-Host "$($_.Name): $lineCount lines"
}

Write-Host "Total lines: $totalLines"

Hi @Adem68 I am getting error like this

This is linux command-line. If you use Windows, you will need to install WSL.

For Windows :

$files = Get-ChildItem -Recurse -Filter *.dart | Where-Object { $_.Name -notmatch '\.g\.dart$|\.freezed\.dart$|\.gr\.dart$|\.gen\.dart$' }
$totalLines = 0
foreach ($file in $files) {
    $lines = (Get-Content $file.FullName | Measure-Object -Line).Lines
    $totalLines += $lines
    Write-Output "$($file.FullName): $lines lines"
}
Write-Output "Total lines: $totalLines" 

Why not this?:
$ find . -name '*.dart' ! -name '*.*.dart' | xargs wc -l
