read_pdf_text 0.0.4

A new flutter plugin project.

read_pdf_text

This is package parses text out of pdf documents and returns it as string. The plugin uses PDFbox open source library.

Getting Started

The package has at this point is only one function getPDFtext(path). Path being the file path to the pdf file you want to parse. I used file_picker package in the example to get the path of a pdf file. Check the example.

        class PDFreaderExample extends StatefulWidget {
		@override
		_PDFreaderExampleState createState() => _PDFreaderExampleState();
		}
		class _PDFreaderExampleState extends State<PDFreaderExample> {
		String _pdfText = '';
		bool _loading = false;

		@override
		Widget build(BuildContext context) {
			return Scaffold(
			floatingActionButton: FloatingActionButton(
				child: Icon(Icons.folder_open),
				onPressed: () {
				FilePicker.getFile().then((File file) async {
					if (file.path.isNotEmpty) {
					setState(() {
						_loading = true;
					});
				
					getPDFtext(file.path).then((pdfText) {
						final text = pdfText.replaceAll("\n", " ");
						setState(() {
						_pdfText = text;
						_loading = false;
						});
					});
					}
				});
				},
			),
			appBar: AppBar(
				title: const Text('Pdf plugin example app'),
			),
			body: SingleChildScrollView(
				child: _loading
					? Center(
						child: CircularProgressIndicator(),
					)
					: Text(_pdfText),
			),
			);
		}

			Future<String> getPDFtext(String path) async {
			String text = "";
				try {
					text = await ReadPdfText.getPDFtext(path);
				} on PlatformException {
					text = 'Failed to get pdf text.';
				}
				return text;
			}
		}
