Here's a step-by-step guide to building the Flutter project you provided, which includes an AI conversation feature using the flutter_gemini package:

Step 1: Set Up Your Flutter Environment

• Install Flutter: If you haven't already, install Flutter on your machine by following the instructions on the official Flutter installation page.
• Set up an editor: You can use an IDE like Android Studio, VS Code, or IntelliJ. Install the Flutter and Dart plugins to enable language support and tools for building Flutter apps.

Step 2: Create a New Flutter Project

• Create Project: Open your terminal or command prompt and run:

  flutter create my_flutter_app

• Navigate to Project Directory:

  cd my_flutter_app

Step 3: Add Dependencies

• In your project's pubspec.yaml file, add the flutter_gemini package under dependencies:

  dependencies:
    flutter:
      sdk: flutter
    flutter_gemini: ^latest_version

• Install the packages by running:

  flutter pub get

Step 4: Implement the Application Code

• Replace the content of main.dart with the code you provided. Ensure to handle the imports correctly and replace the apiKey with your actual API key from Gemini.
• Create a new file named homePage.dart and place the HomePage class code in this file.

Step 5: Run Your Application

• Connect a device or use an emulator.

• Run your application:

  flutter run

  Sure, here is a PowerShell script to convert the delimiter of a CSV file. This script takes three parameters: the input file, the current delimiter, and the new delimiter.

param (
    [string]$inputFile,
    [string]$currentDelimiter,
    [string]$newDelimiter
)

# Check if the input file exists
if (-Not (Test-Path -Path $inputFile)) {
    Write-Host "File not found: $inputFile"
    exit 1
}

# Create output file name by appending _converted to the original file name
$outputFile = [System.IO.Path]::ChangeExtension($inputFile, ".csv").Replace(".csv", "_converted.csv")

# Read the content of the input file
$content = Get-Content -Path $inputFile

# Replace the delimiter
$convertedContent = $content -replace [regex]::Escape($currentDelimiter), $newDelimiter

# Save the converted content to the output file
$convertedContent | Out-File -FilePath $outputFile -Encoding utf8

Write-Host "Conversion complete. Output saved to $outputFile"

How to use the script:

1. Save the script to a file, e.g., Convert-Delimiter.ps1.

2. Open PowerShell and navigate to the directory where the script is located.

3. Run the script with the appropriate arguments:

   .\Convert-Delimiter.ps1 -inputFile "input.csv" -currentDelimiter "," -newDelimiter ";"

This command will convert the delimiter from a comma (,) to a semicolon (;) in the input.csv file and save the result to input_converted.csv.
