flutter pub add read_pdf_text根據套件公開資料產生的選型評估，僅供參考。
read_pdf_text 套件是一個簡單的 Flutter 外掛程式，用於從 PDF 文件中提取文字。它在底層使用 Apache PDFBox 和 PDFKit 來有效解析 PDF 內容。僅需三個簡單函數，即可為需要基本文字提取功能的開發者提供易於使用的介面。適用於需要從 PDF 中讀取或處理文字但不需要複雜格式的應用程式。此外掛程式支援 Android 與 iOS 平台。

This package parses text out of PDF document and returns it as a string.
On Android the plugin uses PDFbox open source library modified by Tom Roush.
The iOS plugin uses PDFKit to parse the text out of PDF documents. It requires iOS version 11 or higher.
For error like: "Could not find or use auto-linked library 'swiftObjectiveC'"

The package only has three functions getPDFtext(path), getPDFtextPaginated(path) and getPDFlength(path). Path is the file path to the PDF file you want to parse. I used file_picker package in the example to get the path of the PDF file.
Check the example for more details.
Returns text from PDF file as a String.
Future<String> getPDFtext(String path) async {
String text = "";
try {
text = await ReadPdfText.getPDFtext(path);
} on PlatformException {
print('Failed to get PDF text.');
}
return text;
}
Returns text from PDF but in a String list, where each item is a page of the PDF file.
Future<List<String>> getPDFtextPaginated(String path) async {
List<String> textList = List<String>();
try {
textList = await ReadPdfText.getPDFtextPaginated(path);
} on PlatformException {
print('Failed to get PDF text.');
}
return textList;
}
Returns length of the document as an integer.
Future<int> getPDFlength(String path) async {
int length = 0;
try {
length = await ReadPdfText.getPDFlength(path);
} on PlatformException {
print('Failed to get PDF length';)
}
return length;
}
